I caught a couple of processing errors in ChatCon when trying to convert the contents of one of my chat windows. Unfortunately, I don't have the time to test it more thoroughly this morning, but given what I've seen of it, it may have something to do with either the name of our org (with [] in it) and/or the org bot & its messages. I'll need to ask Keanne about which bot type we use, because I've noticed that the problem doesn't happen with the chat window into which I send Channel42, so it can't be linked to *any* type of bot, I suppose.
As for the error message I get, it's all in German, but basically I think it means something like "An unexpected error has occurred".

If I manage to reproduce the problem later on -- because, of course, I've deleted my other log without thinking twice. Duh... -- I'll copy/paste it here.
Hope this helps. Anyway, I'll be sending org chat to another window from now on, to see if it goes on and to test again later on.
