Bug 330766

Application: plasma-desktop (4.11.5)
KDE Platform Version: 4.11.5
Qt Version: 4.8.5
Operating System: Linux 3.12.8-200.fc19.i686 i686
Distribution: "Fedora release 19 (Schrödinger’s Cat)"

-- Information about the crash:
- What I was doing when the application crashed:

KDE Crashed when:
- I clicked on app rectangle in taskbar at the bottom, contextmenu appeared
- I clicked "close"
- Popup disappeared, but window was waiting for some time before it disappeared
- I clicked at the same place to make popup appear again
- Popup appeared just when the window closed, like if new context menu had no more underlying app window to be closed (it closed from previous click)

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
