Hello everyone, I posted a fix in this thread here: http://larian.com/forums/ubbthreads.php?ubb=showflat&Number=614713#Post614713

The thread has a minor location spoiler, so be warned. If you can't do the fix outlined there, try looking for any NPC that will automatically talk to you when you get near enough. If you do find one and it worked, please post so that others can see that it also works on other NPCs.

An example would be:
The dog in Stonegarden Graveyard, I think it forces a dialog if you approach.
