When deleting (not moving to Trash) file(s) with the hotkey in the filemanager profile, konqueror sometimes crashes. The files are actually deleted before it crashes. Here is the backtrace:

Using host libthread_db library "/lib/libthread_db.so.1".
`system-supplied DSO at 0xffffe000' has disappeared; keeping its symbols.
[Thread debugging using libthread_db enabled]
