-- Information about the crash:
- What I was doing when the application crashed:
Opened viever (F3) on a html file, selected and copied some text there, closed the viewer (not 100% sure) and switched to another window (not Krusader). After that noticed crash notification.

-- Backtrace:
Application: Krusader (krusader), signal: Segmentation fault
