--- Comment #10 from Erik Dalina edgy.dalina@yahoo.de 2011-04-28 21:40:44 CDT --- Today I installed the new stable Catalyst 11.4.
Of course, the first thing I did was trying out Oblivion -- and guess what ... at least at the one place (and a bit of running around) the crash IS GONE.
Since I don't know if it's the real thing, i.e. _the_ bug/crash is never to occur again or if it's only coincidence, I'll play/test it further in the next days.
And, now I'm pretty sure my case has nothing to do with the conversation engine.
