Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.1 (KDE 4.3.1) "release 6"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.5-0.1-default i686
Distribution: "openSUSE 11.2 (i586)"

What I was doing when the application crashed:
Don't even know.

From time to time, Panel froze, a pop-up window tell me that it didn't find whatever KTT stuff, and then it take minutes to recover, but system still stable, I just have to be patient

Most of the time, it happen when I use the panel (like for windows, it's stable if u don't use it ;) )
mainly, apps that makes it crashing are FireFox, Seamonkey, SunBird and any widget that I try to install or desktop switch or time adjusting and such.

One thing that might help: I lost the "currently open application" panel (so I have to do ALT+TAB to switch) I dunno how it desappears, and most of all I dunno how to get it back !

Panel frozing is just anoying, no big deal, no system crash.
