Sentry Crash Report:

Description Peter Cordes 2015-04-20 22:38:04 UTC 
Application: gwenview (5.0.0 pre)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-14-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
This is a dup of #344809, same crash in the destructor.  drkonqi found that duplicate, but told me I didn't have it selected even when I did.  I'm feeling lazy, so I didn't want to go and manually add stuff to that report  when drkonqi wouldn't.

- What I was doing when the application crashed:

I had two videos playing side by side (selected from the thumbnail picker list).  I clicked deselect on one of them.

keeping this brief since the backtrace matches #344809 exactly, and that report said it was 100% reproducible.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault
