Bug 326848

Application: plasma-desktop (4.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.6
Operating System: Linux 3.10-3-amd64 x86_64
Distribution: Debian GNU/Linux testing (jessie)

-- Information about the crash:
- What I was doing when the application crashed:
1) download new Plasma Widgets: Softraid-Monitor v0.5
2) drag widget onto desktop
3) Plasma Desktop crashed (disappeared for a moment, then reappeared, together with the crash reporting assistant)

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
