Thanks veryy much for this information. I spent a bit of time on it last 
week, desperately trying to find out why the point sprite representation 
causes this dodgyness. I failed. I ended up by having a single 2 line 
xml entry with nothing in it at all, and this caused the error. I tried 
cloning other ones and everything - but it seems like as soon as I add a 
new anything to the representations this error comes back.

Can anyone tell me what the error really means?

I tried adding methods for GetDocumentation, tried adding xml entries 
for doc, removing them, everything, but since I don't really know what 
the rror message is trying to tell me, I am clueless - what is the 
NoneType object referred to, and why is the doc not found?
