Hello,

This is hard to reproduce, because it seems like a random behaviour. Anyhow, below you will find a tracelog.

After deleting some files (trash, but most of the times when deleting permanent, can't remember exactly) or even once while moving files (not this tracelog).

Also see this thread on dot.kde.org: http://dot.kde.org/1117548502/1117623146/

Tracelog (as showed after the crash):
