Application: kwin (4.3.80 (KDE 4.3.80 (KDE 4.4 Beta1)) "release 197")
KDE Platform Version: 4.3.80 (KDE 4.3.80 (KDE 4.4 Beta1)) "release 197"
Qt Version: 4.6.0
Operating System: Linux 2.6.31.5-0.1-default i686
Distribution: "openSUSE 11.2 (i586)"

-- Information about the crash:
Kwin crashed when clicking "Show hidden icons". 

As for dublicates, i found possible dublicates, but they are already closed. 
My kde setup was last updated in ~evening 09'-12-11, so if they there closed later, close this bug to (i'm currently updating to se if i could reproduce later) :)

 -- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
