Comment 9 for bug 1346567

Thanks for the backtraces. It became clear when I observed the output that you were using glib from a PPA that was an unofficial repository. Upon looking at your attached dependency list I believe the reason this crashes on your system and not a stock 14.04 is related to this:

libglib2.0-0 2.41.2~git20140714.79e63d4e-0ubuntu1~14.04~ricotz0 [origin: LP-PPA-ricotz-testing]
libglib2.0-data 2.41.2~git20140714.79e63d4e-0ubuntu1~14.04~ricotz0 [origin: LP-PPA-ricotz-testing]

You seem to be using Rico Tzschichholz gnome-testing which can make a system unstable. In particular I have identified the glib entries above since I believe they are the heart of the problem. It appears that there is likely a bug being detected in GNUbg because of new checks that were added to recent versions of glib. This is most likely a GNUbg bug, I would have to investigate further when I get a chance to try the new glib out on a system.

I believe the recent changes to GLib that likely influence this bug is this set of patches (see the part about detecting some mutex bugs):

I believe if you were to downgrade glib back to the official Ubuntu version that GNUbg would run albeit it with a bug that is likely going unnoticed. If you could verify that the official glib works then we have an explanation as to why your system is being affected and not others.
