[network]: gnome-control-center crashed with SIGSEGV in refresh_ui()

HP-Envy 14 (laptop)
Version
      1:3.4.1-0ubuntu1

Gnome 3 GUI crashed and keyboard, including power button (with the exception of a hard power off), became non-responsive. Open applications on the current desktop were still displayed and mouse input still functioned but without the gnome shell it was impossible to log out, power down, open applications, etc... Restarting corrected the issue but this has happened half a dozen times.(On another partition with 12.04 on the same machine. This report was filed under a fresh upgrade.)

It seems to be random as no specific program causes the crash, although most of them (4 out of 6) occurred while either using update manager or another package manager (synaptic).

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

The duplicate status seems to be wrong. The alleged duplicate (bug #672930) is "Feature request for movie export menu: display zoom scale".

I seem to be having the same bug, though my laptop doesn't freeze, only the System Setttings menu closed.
Running 12.04 64-bit with unity, only things installed are Google Chrome v. 20.0.1115.1 dev and Synaptic.

Booted AMD x64 Desktop CD as "Try Ubuntu" on my desktop machine to see how it would handle my FireMV video card. No install done - I'm running the live CD. 8GB memory.

Went to the Dash Home, typed "n", selected Network.
Selected All Settings. Selected Network. Died.

Repeatable. Every time. I can open any number of other Settings entries, but I can't open Network twice. It always dies on the second try. Once, even opening another Settings icon also caused it to die (after starting with Network).

I have one onboard 1G NIC, two PCI 100M NICs, one USB 1G NIC (that's four "Wired" entries).

Hey Mathieu, could you look at this bug, it seems similar to bug #912948, it's still showing up on the whoopsie reports but it could be because the update didn't move to updates yet

[Mathieu Trudel-Lapierre (cyphermox)]

This is indeed the exact same thing as bug 912948; the interface crashes because a hidden AP is in range, and gnome-control-center doesn't cope.

I'll mark this bug as a duplicate of 912948, if you're having that problem, please see on the other bug report for how to enable the -proposed repository and testing the new package so that we can ship this as a stable update. Thanks!
