Stasks segfaults plasma-desktop in KDE 4.4

[Invader Zim]

Binary package hint: plasma-widget-stasks

1. Install KDE 4.4 from kubuntu ppa (or some other source)
2. Install stasks from kpackagekit
3. Add stasks widget to the panel
4. If no program window is on the taskbar, open one
5. plasma-desktop crashes

Showstopper for non tech end user. Cannot easily revert back, only through manual editing of a text file.

Package should be changed to allow only KDE 4.3 (or previous versions if verified it works) until verified it's updated to work with KDE 4.4.

Kubuntu 9.10
