it is all of the side girls.. here is an example of when it happens (if you click "Close" on this window) 
and heres a copy/paste of teh BB code, as im not sure which the 'main lines' would be :)
like i said, it doesnt really break the game, you can click ignore or rollback and it goes straight back to the game.. it only happens if there are no remaining hints for the girl.
i only mention it cos newer players might be put off.
[code]
I'm sorry, but an uncaught exception occurred.
While running game code:
