looks like you were in a folder selection dialog and the folder contents was changes (either file removed, add or renamed). could you please try reproducing this crash with KTorrent for KDE5 Frmaeworks?
Comment 2 Germano Massullo 2016-02-16 09:33:35 UTC 
I tried to reproduce the crash using KTorrent for KDE5 Framaeworks, but the crash did not happen
