GTK3 schema patch for Firefox 60 none

Description Paul 2018-06-29 19:22:16 UTC
Created attachment 1455568 [details]
GTK3 schema patch for Firefox 60

Description of problem: Some window prompts (such as "Browse...") cause Firefox 60ESR to crash as it cannot find a gsettings schema.

Version-Release number of selected component (if applicable):

How reproducible:
Every time. 

Steps to Reproduce:
1. Open Firefox 60 ESR on RHEL6
2. Browse to any page that has an attachment or browse button (such as this one, "Add an attachment")
3. Click Browse/Attach

Actual results:
Firefox Crashes

Expected results:
Firefox displays a GTK3 file system window

Additional info:

I have a "patch" that adds the env declaration to the launch wrapper. See the attachment.

Comment 2 Paul 2018-06-29 19:25:23 UTC
Terminal output during the crash:

(firefox:30405): GLib-GIO-ERROR **: No GSettings schemas are installed on the system
Trace/breakpoint trap (core dumped)

Comment 3 Martin Stransky 2018-07-02 06:21:47 UTC
Jan, can you please look at it? Thanks.

Comment 4 Paul 2018-07-03 12:51:27 UTC
This happens with any GTK3 file browse window, so we have come across an easier way to reproduce this.

1. Open Firefox 60.1.0 on RHEL6
2. File -> Open File...

Comment 7 masanari iida 2018-07-04 08:26:14 UTC
I have encountered this symptom on my local test box.

The OS was installed from RHEL6.8 DVD sometimes ago,
and I have updated firefox 60 RPM and dependencies.


I can reproduce the crash 10 times in 10 tests.
From top Menu,  File -> open
Right Click on a link -> Select "save as"

reason (collected by abrt)
Process /usr/lib64/firefox/firefox was killed by signal 5 (SIGTRAP)

In messages,
kernel: firefox[3351] trap int3 ip:7f60a73eb5bf sp:7ffdf728e2f0 error:0

Comment 8 masanari iida 2018-07-04 08:48:35 UTC
Apply the patch on this BZ case, it resolved the issue for me.
In order to double check, I removed the patch and the symptom come back again.

Comment 10 Joe Wright 2018-07-09 15:20:44 UTC
Occurs with both 32 and 64 bit versions

Comment 12 Jean Redfearn 2018-07-09 19:02:30 UTC
The patch did not change anything on our systems (RHEL6.10 with gtk2).
We also see segfault from libzul.so in /var/log/messages

You might be hitting different issue, please file a new bug for it or use customer portal to report it. 

If you wish you can attach a stack trace to the new bug by:
debuginfo-install firefox
firefox -g
(wait for crash)

Comment 15 Michael Boisvert 2018-07-11 15:37:10 UTC
I can confirm using the reproducers in the bug description and comment 4, that an appropriate GTK3 file browse window successfully pops up when issuing various browse, add attachment or file open commands in firefox-60.1.0-6.el6.

Comment 16 Akemi Yagi 2018-07-12 22:48:17 UTC
I, too, can confirm that the provided patch fixes the issue.

Comment 17 Pavel Kankovsky 2018-07-16 16:12:56 UTC
XDG_DATA_DIRS should probably be set to something like "$MOZ_LIB_DIR/firefox/bundled/share:${XDG_DATA_DIRS:-/usr/share}".

XDG_DATA_DIRS="$MOZ_LIB_DIR/firefox/bundled/share" (that is without any reference to standard data dirs) seems to break external viewers such as Evince. FF is unwilling to run them (or even to offer to run them) and when you convince FF to start them, they are likely to fail anyway.
