Bug 236082

Application: dolphin (1.4)
KDE Platform Version: 4.4.3 (KDE 4.4.3)
Qt Version: 4.6.2
Operating System: Linux 2.6.33-3.slh.4-sidux-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
I upgraded from KDE 4.3.4 to KDE 4.4.3 on my sidux machine.I wanted to resize the position of the search bar, since it it either to small or consumes all of the left-over space on the toolbar. I did not succeed and now when I start Dolphin it shows me a misplaced search bar in the middle of the toolbar as well as a second small window titled "dolphin" that shows nothing except a part of my desktop. When I try to close it, it closes but after a couple of application restarts Dolphin crashes.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
