1383895 - Whenever a file listing is requested, Firefox crashes. EVEN after a refresh

Status: RESOLVED WORKSFORME

(Core :: Widget: Gtk, defect)

Description

[George R. Goffe]

I'm sure that there are a number of crash reports for this problem under my id(?) or under this system name(?). The problem appears even in safe-mode.

I did a refresh in the hopes that this would resolve the problem. It did not solve the problem. I have re-installed most of the add-ons and done some customization.

Am I doing something wrong? Could be but I've been using FF for a rather long time. This is the first problem like this that I've encountered.

Your help would be greatly appreciated.

More info...

I can get this crash from any print dialogue, ctrl-p and then selecting print to a pdf and then trying to browse for a filename. The instant I poke the browse button, the crash happens.

Help!!!!! please...

George...

Most of us can't search our crash database for personal information like this. We're quite careful about privacy like that...

Can you point us to crash reports for this by going to about:crashes and opening the ones submitted from there? This is assuming you're using an official mozilla.org build that has crash reporting enabled (rather than, say, a build from your distro).

Hi,

THANK YOU FOR RESPONDING.


After running firefox under gdb (Fedora 27 x86_64 (rawhide)) I got a stack trace at the point of the exception.

Comment 5

[:Gijs (he/him)]

Thanks. The crashes listed on about:crashes are all relatively old. The stack you got from gdb implies that there's an issue in GTK code, though the fact that the stacktrace portion that's from firefox (libxul.so) has no symbols doesn't help.

Karl, is this something you can make sense of and/or do you have other suggested steps for how to figure out what's happening?

Comment 6

[George R. Goffe]

Gijs,

I'm trying to find debuginfo for libxul... If I find (and install) it, I'll rerun the gdb... and post the results. Unfortunately this bug is trivial to recreate. Sigh...

George...

[Jan Horak [:jhorak]]

Hi, it seems that you have Fedora rawhide. In this case you most likely hit:
https://bugzilla.redhat.com/show_bug.cgi?id=1472819 - regression in gvfs library. Read the bug for more info and how to fix it.

Comment 8

[George R. Goffe]

Jan,

Thank you for this information and your (everyones) hard work. I'll test again and post the results here.

George...

Comment 9

[George R. Goffe]

Jan,

Here's the latest gdb backtrace. I'm wondering how to get debuginfo out of libxul.so. 

Thanks,

George...

Comment 10

[Karl Tomlinson (:karlt)]

libxul debug info is probably not going to help much, as the stack already indicates that this is processing an event on the main context.

I suggest trying gvfs 1.33.1 to confirm this is https://bugzilla.redhat.com/show_bug.cgi?id=1472819
Thank you, Jan for tracking down its cause.

Karļ

I have a fix from redhat for gvfs-1.33.3 (et. al.) and it works great!

Thanks to everyone who helped with this.
