Description GongT 2013-10-30 13:37:13 UTC

KDE Platform Version: 4.11.2
Qt Version: 4.8.5
Operating System: Linux 3.11.6-200.fc19.x86_64 x86_64
Distribution: "Fedora release 19 (Schrödinger’s Cat)"

-- Information about the crash:
this problem comes from the kde default taskbar plasmoid created by Eike Hein.
--
Here is a java program, it will take a few time to close.
Now I close it by right click it's icon in the taskbar.
when the program is cleaning itself.
I right click it's taskbar icon and try to close it again.
between the click of program's icon and "close" menu item, this program ended successfully.
then plasma-desktop crashed

The crash can be reproduced every time.
