Video showing the segmentation fault (335.85 KB, video/webm)
2014-03-31 02:15 UTC, Conley Moorhous 		Details

Description Conley Moorhous 2014-03-31 02:13:15 UTC 
Toggle the setting (i.e., on and then off) twice and it will segfault. In other words, click the toggle four times. I just installed this from the [gnome-unstable] repo on Arch Linux, but I will try to build it with debugging enabled in jhbuild soon.

Video showing the segmentation fault

Note that, in this video, the bug occurs after only toggling on and off once. This is what happened the first time I encountered the bug, but it sometimes doesn't occur when toggling once.

I am getting the same backtrace. However in my case it is enough to play a FLAC file (MP3/MP4 appear to be unaffected). It will crash shortly after the seekbar is hidden. If I keep the seekbar visible by moving the mouse it plays fine. Visual effects are disabled, so the cover will be displayed.

Looks like a bug in cogl. The crash actually happens quite a bit of time before.

It works fine on my system after I've updated to cogl 1.18.0. Which version of cogl are you using? (It was working on my system-wide version of totem, but not in jhbuild because cogl wasn't updated).

Looks like it. Apparently my last try got a little further and printed this critical (after lots of criticals referring to Grilo) before crashing: 

(totem:19674): Cogl-CRITICAL **: file ./cogl-rectangle-map.c: line 514 (_cogl_rectangle_map_remove): should not be reached

For me that would be the one from the F20 COPR which should be 1.18.0 as well. But I also gave the one in jhbuild a try and the result's the same.

I was using 1.18.0 in Arch Linux' [gnome-unstable] repository, but I got the same result with jhbuild.

Given that the problem only seems to happen on Arch Linux, and I can't reproduce the problem at all in Fedora 20 + COPR (that's GNOME 3.12), I'd encourage you to file a bug against your distribution. Hopefully you'll find a sure fire way to reproduce the bug that I can use.

FWIW, I'd point towards a Mesa, X driver or kernel bug that's hardware specific. Might be good to check in that direction.

Reopen this bug when you have some more debugging information, or a reproducer.

JFYI, I could reproduce it on two different F20 + COPR machines here and may have spotted the cause of it in Cogl (not entirely sure though): bug 728064.
