Sometimes when I permanently delete (Shift+Canc) one or more file/folders with Dolphin, the delete dialog hangs there.
It doesn't depend on the size, because it can happen with 1kb single file too.
When I click "cancel" in the dialog, Dolphin crashes:

Application: Dolphin (dolphin), signal SIGSEGV
Using host libthread_db library "/lib/libthread_db.so.1".
