Hi, you'll need to provide a stacktrace so that we can see where it's crashing. The easiest way to do this would be via the built-in Problem Reporting tool, but you can also do it manually following the instructions at https://fedoraproject.org/wiki/StackTraces Created attachment 1248658 [details]
GDB strack trace of Epiphany crash
It looks like WebKit is trying to use GtkSocket in Wayland. That's probably a security issue actually. But we need a much better backtrace. You'll need to install the necessary debuginfo packages before taking the backtrace. Also, for some reason it's cut off at thread seven, so we can't even see the crashing thread. I think the easiest way to proceed here would be to report the bug using the Problem Reporting application that's installed by default in Workstation. The hardest task here would be to figure out where in the preferences dialog to configure your Red Hat Bugzilla credentials; it's not a great user interface, but shouldn't be too hard. Alternatively, when running gdb, look for the 'dnf debuginfo-install' command given by gdb, execute it, quit gdb, and wait for it to finish. (It may take a long time.) Then try to get the backtrace again now that you have debug symbols installed. We need the debug symbols to see where the program is crashing. When generating the backtrace, make sure to keep pressing Enter until you've reached the bottom; in the trace you attached above, you stopped for some reason halfway through, missing the thread that actually crashed.

new gdb stack trace for Epiphany and audio problems
I attached a new gdb trace text file although when running gdb Epiphany after using dnf to debuginfo-install, Epiphany would not crash in that environment although it still crashes running directly from gnome desktop exactly as before. Gnome Problem Reporter seems to resist sending a report of the crash but my last attempt to do so resulted in: Epiphany killed by SIGSEGV - abrt --- Running report_uReport --- The server at 'https://retrace.fedoraproject.org/faf' encountered an internal error (got error 500) reporter-ureport failed with exit code 1 ('report_uReport' exited with 1) --- Running report_EmergencyAnalysis --- Compressing data Sending /var/tmp/ccpp-2017-02-08-11:41:31-3123.tar.gz to https://retrace.fedoraproject.org Successfully created https://retrace.fedoraproject.org/faf/dumpdirs/new/ccpp-2017-02-08-11:41:31-3123.tar.gz <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN"> <title>Redirecting...</title> <h1>Redirecting...</h1> Let me know if there is anything else I need to do. I'm not an expert in debugging Linux software and these tools are now to me. -Pv- My next attempt was to run Epiphany directly from command line instead of gnome desktop icon. The application window opens, tries to display the last URL and result: epiphany Vector smash protection is enabled. (epiphany:6568): Gtk-WARNING **: GtkSocket: only works under X11 (epiphany:6568): Gdk-WARNING **: gdkwindow-x11.c:5573 drawable is not a native X11 window Segmentation fault (core dumped) Created attachment 1248897 [details]
another dgb back trace of Epiphany freeze which looks different from the others
More: Running "dbg epiphany" as su does not crash or freeze but has the PulseAudio problem. Running same as normal user crashes or freezes. -Pv- Don't try to run anything as root. That's not expected to work! Attachment #1248897 [details] is what I was looking for. In the future, please use 'bt full' rather than 'bt' so that we can see stack frames, but this time plain 'bt' was enough: we know that it's coming from WebKit::WebPageProxy::createPluginContainer. So I'm pretty confident that you're hitting https://bugs.webkit.org/show_bug.cgi?id=163159. Problem is, we don't know why that crash happens! So can you please check two more things. First, run this command in a terminal and see what it prints: $ echo $WAYLAND_DISPLAY I'm expecting it to print "wayland-0". If so, then it's a bug that WebKit::WebPageProxy::createPluginContainer is being called at all. We should never attempt to display windowed plugins in Wayland. Next, could you please navigate to the page about:plugins in Epiphany and let me know which plugins you have installed? This page is expected to be kinda broken due to https://bugs.webkit.org/show_bug.cgi?id=164102, but it should at least give you an indication of which plugins you have installed. *** Bug 1420909 has been marked as a duplicate of this bug. *** In particular, do you have Flash installed? I guess so! $ echo $WAYLAND_DISPLAY wayland-0 is the result I get. about:plugins result: Shockwave Flash Shockwave Flash 24.0 r0 Enabled: Yes MIME type Description Suffixes application/futuresplash futuresplash player spl application/x-shockwave-flash shockwave flash swf Note: This is the default installed condition. I have not modified the plugins nor do I know how in this application. I would never use the itunes plugin so would be interested in disabling it. Also, foxnews.com uses HTML5 player. -Pv- iTunes Application Detector This plug-in detects the presence of iTunes when opening iTunes Store URLs in a web page with Firefox. Enabled: Yes MIME type Description Suffixes application/itunes-plugin (null) OK thanks, let's track this in the upstream bug https://bugs.webkit.org/show_bug.cgi?id=163159. That's not the default installed condition, by the way; you clearly installed Flash, which is what's causing it to crash. The iTunes plugin is coming from Rhythmbox, so to get rid of that you'd have to uninstall Rhythmbox. That really is installed by default. The plugin should probably be split into a subpackage so that it can be removed without removing Rhythmbox itself. *** This bug has been marked as a duplicate of bug 1382789 *** |
