Bug 383702

Application: gwenview (4.14.0 pre)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 8.9 (jessie)

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

I unmounted a drive and noticed that Gwenview crashed. I guess it displayed a folder from that drive.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
