Bug 185063

Version:           unknown (using 4.2.00 (KDE 4.2.0), Debian packages)
Compiler:          cc
OS:                Linux (x86_64) release 2.6.26-1-amd64

i launched kfind from Dolphin's menu while at some Tab.
kfind worked ok (returned some good results) i copied some of the items
to some other open Tab in Dolphin.  (copy&paste)
closed the original tab (from which the kfind session was launched) 
an after awhile (working with other applications) i saw kfind is still open on the task bar
and i tried to close it and it crashed.

see crash report:
