Bug 200138

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
Qt Version: 4.5.2
Operating System: Linux 2.6.31-2-generic i686
Distribution: Ubuntu karmic (development branch)

What I was doing when the application crashed:
mouse over a folder view plasma on desktop shows popup of unplugged, usb stick folder, (probably leftover) and crashes KDE.
Other folder popups work fine,

 -- Backtrace:
