Bug 221308

Application: plasma-desktop (0.3)
KDE Platform Version: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-17-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
When waking from suspend to RAM after my laptop had automatically gone to, "sleep" (due to low battery), waking it up once succeeds, but then the  laptop goes to sleep again. On the second wake-up, the laptop stays on, but plasma crashes with the following output.

Possibly related is that I am using the gnome network manager applet, and that it (theoretically) had to re-connect to the network I was using twice in a short amount of time, once for each time the laptop suspended to RAM.

The crash can be reproduced some of the times.

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
