I can confirm this; it was working fine until I updated this morning. Running lancelot in the command line (which used to pop up the menu) gives:

Caused by an API change introduced by the Plasma Tooltips patch to kdebase-workspace. More, specifically, the taskmanager lib calls.

Actually, just binary incompatibility. Throwing this puppy up for a rebuild should fix it.
