Application: gwenview (4.12.2)
KDE Platform Version: 4.12.3
Qt Version: 4.8.5
Operating System: Linux 3.13.6-200.fc20.x86_64 x86_64
Distribution: "Fedora release 20 (Heisenbug)"

-- Information about the crash:
Steps to reproduce the bug
1. Open an svg file in gwenview
2. Modify the image using another application
    In my case I was using graphviz's 'dot' to regenerate the svg file.
3. Switch to gwenview and reload the image using F5.

The crash can be reproduced every time.

-- Backtrace:
