can't really track this down right now but as i'm just reorganizing my disks it
happened a couple of times now..

right before the troubling assertion i added a kDebug that dumps the hash list
checked for the item.. example output for a crash followin.

KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = konqueror path = <unknown> pid = 9845

so here _k_slotDeleteItems gets invoked with the old file path for whatever
reason. It happens fairly frequently when you rename/move stuff within a folder
structure, should be easy to replicate. Sorry no fix yet here..
