Bug 315350

Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.5 (4.8.5) "release 2"
Qt Version: 4.8.1
Operating System: Linux 3.4.28-2.20-default i686
Distribution: "openSUSE 12.2 (i586)"

-- Information about the crash:
- What I was doing when the application crashed: closing Konsole after very little activity - had mounted and unmounted a windows partition in an attempt to make the ntfs partition look "not busy"

-- Backtrace:
Application: Plasma Desktop Shell (kdeinit4), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
