-- Information about the crash:
- What I was doing when the application crashed:
An image was displayed (from a removable device) in Browse view. When I opened the sidebar and changed its tab to Folder, Gwenview changed the directory and started playing the first video file in the root folder of the mounted device. FAULTY BEHAVIOUR
After trying to change the path back the app crashed.

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