AU Lab crahes while loading plug-In "CantTutThis"

I just installed AU Lab

It crashes during AU scan.

I get this error message (german):

"AU Lab wurde beim Verwenden des Plug-Ins CantTutThis unerwartet beendet."

There´s no such AU in my components folder...

My DAWs work - no AU problems, only with this tool (Downloads for Apple Developers)

Any ideas ?
