Latest tip, jucer crashing

I downloaded the latest source(last night that is), and build the new Jucer(winXP). It runs fine until I try to add files to my project, then it breaks at
jassert (changeListenerList.isValidMessageListener());
Line 54 of juceChangeBroadcaster.cpp
Anyone else having this problem?

I’ve got a few changes pending that’ll probably sort that out - will be checking in later today…
