Stuck - cant continue bug - cant close dialog with guard

How to make it.
1. Wolgraf steal in Evelyn's shop. Not chained to rest of party. Multiplayer is not active.
2. Wolgraff spotted so Guards called
3. Wolgraff make Shadow walk and run away
4. Other party members, stay in shop. None attacked them
5. Main character talks to the called Guard in the shop. (I wish I could convince them to let Wolgraff go, pay a fee or something)
6. Dialog window popups, but no text from guard, no option to answer, no way how to end dialog. Just empty window.
7. Also tried to attack talking guard with another char, but it seems the persons in dialog are invulnerable.
8. Cant continue ---> an old save used :-/
