I think I've got the same bug. A couple of weeks before I've hit this with Linux Mint also. I investigated then and the problem was that the network applet registered callbacks for events (network disconnection etc.) but failed to unregister them when the applet was unloaded. Because of this, the callbacks would be called again with freed memory addresses as parameters.
Steps to reproduce: Open gnome-control-center, and after that the network panel. Toggle the wired connection ON->OFF (I have a wired one), then OFF->ON. Exit network panel to gnome-control-center and then reenter network panel. Crash. From what I remember using Valgrind took a couple (4, 5 at max) of entering, exiting the network applet before a crash would occur. Using the Ubuntu compiled version would get me a crash directly. I'm using Ubuntu quantal (development branch) AMD64, gnome-control- center 3.4.2. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/803631 Title: gnome-control-center crashed with SIGSEGV To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/803631/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
