Description matthias sweertvaegher 2010-01-31 15:07:08 UTC 
Application: plasma-desktop (0.3)
KDE Platform Version: 4.3.95 (KDE 4.3.95 (KDE 4.4 RC2)) "release 214"
Qt Version: 4.6.1
Operating System: Linux 2.6.31.8-0.1-desktop i686
Distribution: "openSUSE 11.2 (i586)"

-- Information about the crash:
i was dragging the configure desktop icon from the kickoff favorites into the quicklaunch widget which resides in my main panel. After that I tried to change the order of the icons in the quicklanch widget by dragging the freshly added icon to a new position. I am not sure though at which point exactly plasma crashed. It may have been the initial drag or the second one for rearranging..

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault

I also notice this crash but when dragging the msot left icon in quicklauch to some right position (for example, I have icon for dolphin, kopete and chrome and I drag dolphin icon between kopete and chrome)

The same (KDE 4.4, Archlinux x86_64). I accidentally dropped an icon from quicklaunch to the desktop, plasma-desktop crashed immediatelly.

From bug 228102:
-- Information about the crash:
I put my quick launcher on the desktop and was trying to drag around an icon
from the launcher. After releasing the icon (can't say whether onto the quick
launcher itself or onto the desktop) plasma crashed.

Comment 6 Ingomar Wesp 2010-05-01 02:02:27 UTC 
Should be fixed in SVN r1121230 (actually, this was probably fixed back in revision 110884).
