Yes, this analysis is correct I think, and I don't see any work-around 
for that problem. I'll hurry with the fix =)

I'll register this as a suggestion, but I'll start by just silencing the 
exceptions and avoiding the crash (which means that properties and slots 
which use classes that are not on the class path will not be 
introspectible from C++, which I hope is acceptable for you for the time 
being).

I'll let you know when a patch is ready.
