Bug 234631

Application: kate (3.4.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2) "release 239"
Qt Version: 4.6.2
Operating System: Linux 2.6.31.12-0.2-desktop i686
Distribution: "openSUSE 11.2 (i586)"

-- Information about the crash:
I ran into this crash when I tried to launch Kate. The backtrace shows that the crash is inside Solid's volume handling. It might be caused by the fact that I had unplugged my (LUKS-encrypted) external HDD while having suspended the system. The output of `mount` suggests that the device is still mounted:

/dev/mapper/externaldrive on /externaldrive type ext3 (rw)

The crash can be reproduced every time.

 -- Backtrace:
Application: Kate (kate), signal: Segmentation fault
