Status changed to 'Confirmed' because the bug affects multiple users.

After applying my patch to bug 908670; I can't manage to crash the network panel at all. I suspect this is really just another instance of the same crash, hidden somehow since it would depend on how the crash gets triggered.

Hello Tormod, or anyone else affected,

Accepted gnome-control-center into precise-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

If you can reproduce this bug, please see Martin Pitt's comment to enable the Proposed repositories and update to the new gnome-control-center package for testing.

There issue has no specific steps to be triggered but the fix seems fine, no regression was reported and the capplet works fine here, setting as verification-done

This issue occured in gnome-shell, i using unity now, and does not appear.
