Crashes on right-click after waking up from suspend

Running under the awesome window manager. Haven't tested while running under xfwm.

Xubuntu 12.10
Linux monolith 3.5.0-18-generic #29-Ubuntu SMP Fri Oct 19 10:26:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

How to reproduce:
1. Start xfce4-power-manager
2. Right click icon in notification bar and choose "Suspend"
3. Wait for computer to go to sleep and wake it up again
4. Right click icon in notification bar: Crash due to segfault, backtrace stops in libgtk-x11-2.0

Backtrace from the core dump:
