This bug would be more informative, if you enabled proper crash reporting as described on https://wiki.ubuntu.com/Apport#Ubuntu_12.04_and_later.

I am attaching stack traces for both of them. ** Attachment added: "stacktrace1.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-flashback/+bug/1639616/+attachment/4774026/+files/stacktrace1.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1639616 Title: gnome-flashback crashed with SIGABRT() in g_assertion_message() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-flashback/+bug/1639616/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
