The unref in BackgroundLoader.ready_cb seems to be the issue here, from commit http://bazaar.launchpad.net/~unity-greeter-team/unity- greeter/trunk/revision/367
At least on my system, after the updates to glib 2.32 and gtk 3.4, the first BackgroundLoader that is created always ends up in ready_cb with only one ref, so we destroy ourselves before trying to access the images pixbuf array. This seems to be because there is a size_allocate before the image finishes loading, so the BackgroundLoader hash table is cleared, which would destroy the BackgroundLoader if we didn't have the extra ref in BackgroundLoader.load. It may be the case that the extra refs, unrefs added in that commit are no longer needed with the library upgrades (although if that were the case, I think we would see more duplicates...), but my thought is just to move the unref in ready_cb to the end, so we can finish up whatever we are doing in case the unref destroys us. Either of the above seem to fix the crash here anyway. ** Branch linked: lp:~jconti/unity-greeter/fix_967343 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/967343 Title: unity-greeter crashed with SIGSEGV in background_loader_ready_cb() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-greeter/+bug/967343/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
