I get this same backtrace when running /usr/bin/liferea, but /usr/bin/liferea-bin seems to work fine. It looks like /usr/bin/liferea sets the LD_LIBRARY_PATH, which leads to the segfault somehow. [lmacken@crow ~]$ /usr/bin/liferea-bin A stale lockfile has been found, and was deleted. ** (liferea:4576): WARNING **: Failed to open HTML widget module (/usr/lib/liferea/liblihtmlm.so) specified in configuration! libgtkembedmoz.so: cannot open shared object file: No such file or directory trying to load browser module GtkHTML2 (liblihtmlg.so) ERROR: No output during decompression (Liferea then loads fine.. happiness ensues) [lmacken@crow ~]$ export LD_LIBRARY_PATH=/usr/lib/mozilla-1.7.13: [lmacken@crow ~]$ /usr/bin/liferea-bin Segmentation fault So, it crashes in the d-bus code, but only if it uses mozilla for rendering? Neat trick. *** Bug 200698 has been marked as a duplicate of this bug. *** Because it is using threads if it is using mozilla and threading must be initlized: g_thread_init() gdk_threads_init() dbus_g_thread_init() Liferea upstream ought to have interest in examining this. With an added early call of dbus_g_thread_init and rebuilding against firefox-devel, liferea crashes in the Mozilla rendering plugin instead of dbus. That is a step. Do you have a backtrace? This supposedly has been fixed 1.0.19, but I haven't had a chance to look to see if it actually works yet. https://sourceforge.net/tracker/?func=detail&atid=581684&aid=1523428&group_id=87005 $ rpm -q liferea

Looks like this bug has been around for a while. Here's a link to it: https://sourceforge.net/tracker/index.php?func=detail&aid=1455278&group_id=87005&atid=581684 I've added comments to that bug.
There is a work-around included in there. Calling
gtk_moz_embed_set_comp_path("/usr/lib/firefox-1.5.0.5")
makes the plugin work so far. Instead of hardcoding it, it would
be easy to make it evaluate an environment variable passed in from
the liferea shell script.
Another problem is in the /usr/bin/liferea wrapper, which messes up
looking for the Firefox home. Basically, it has got the home directory
right, but strips off two directories and then ends in /usr where it
doesn't find the libraries. ;)
Looks like version 1.0.20, should fix this. This should be fixed w/ 1.0.20. If you still have problems, please re-open this bug. |
