Bug 317955

Application: plasma-desktop (0.4)
KDE Platform Version: 4.10.1
Qt Version: 4.8.4
Operating System: Linux 3.8.4-202.fc18.x86_64 x86_64
Distribution: "Fedora release 18 (Spherical Cow)"

-- Information about the crash:
- What I was doing when the application crashed:

When I disconnect BlackBerry Z10, the applet sometime crashes. This is because BB creates usb0 network device, which suddenly disappears when the USB cable is unplugged.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
