Hold on; I think I just verified a stealing bug that someone reported. Take coins that you own, and just place a portion of them on the ground. The ones dropped aren't marked as belonging to you, so moving you will get you accused of stealing.
I get accused of stealing for eating food off the ground/table/inside-crates in caves and abonded places. If I first put the food in my inventory and then eat it I don't get accused, go figure.
Actually no it was nothing like that. I was in Trinsic taking stuff from the back room of the armorer when he said "Dont touch that" after I toook one thing, then I went to take a second and he called the guards!
