[p4-feedback] Null pointer exception when changing the active ontology

Oops! I've just tried the same, but didn't get any exception. I've  
opened koala from its original location and went through 1-3.  
Everything is fine here.

I've also got version 4 b113 on a Mac. (Mac OS 10.5.8, 2.4 GHz Intel  
Core 2 Duo -- in case this is of interest).

Cheers

Thomas
