Bug 248357

Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-24-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
When suddenly my digital-clock plasmoid disappeared in the panel, I tried to readd it. First I tried to add it to the panel directly via rmb/Add applet which didn't work for some reason.

Then I dropped the applet onto the desktop (it appeared), from there I tried to drop it onto the panel which didn't work.

Then I opened panel settings from rmb/settings for panel and then I tried to drop the digital clock onto the panel.

First I found no suitable spot (crossed drop cursor), then the cursor became enabled just between the embedded window plasmoid and desktop switcher. When I dropped it there, plasma crashed.

Backtrace resembles that of bug 192000, but it's not the same.

I cannot reproduce the bug as Plasma doesn't let me add *anything* to the panel since then.
I tried with styles Air and Aya, but it makes no difference.
