Application: dolphin (1.4)
KDE Platform Version: 4.4.4 (KDE 4.4.4) "release 8"
Qt Version: 4.6.3
Operating System: Linux 2.6.34-12-desktop i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
opensuse 11.3 (32bits) / kde 4.4.4 from repo kde:/distro/stable

Just after opening my kde session (so nepomuk & virtuoso are running hard )
I open dolphin, navigate 3 subfolders and make a selection with ctrl+a
when I hit the ctrl key to unselect directories, dolphin crash.

PS : at this time I've clean all /tmp/kde-* at the end of the previous session

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Dolphin (dolphin), signal: Aborted
