Unknown; was exiting software center

[MetalSonic v3]

Binary package hint: kdebase-workspace

Just upgraded to Karmic. Ubuntu Software Center was not running in GNOME with Remix Launcher at first; it worked after running it in KDE. However, when I tried to log out from KDE(I was trying to see if it was a WM issue), it took a long time and when I logged into GNOME and ran it again, when I closed Software-Center, I got a crash warning. apt-cache says that I have kdebase-workspace version 4:4.3.2-0ubuntu7.
