Have you been able to reproduce this recently? Unfortunately, it seems like the backtrace here doesn't contain anything useful, and I also can't successfully retrace it to get anything meaningful for a good debugging session...
I'd be tempted to leave this as Incomplete until we can reproduce this bug in the current versions of NetworkManager and Glib. ** Changed in: network-manager (Ubuntu) Status: New => Incomplete ** Changed in: network-manager (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1224395 Title: NetworkManager crashed with SIGSEGV in g_type_check_instance_cast() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1224395/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
