When I first encountered the Undead Merchant (adventurer weapons), I obviously pickpocketed her. After doing so I usually reorder my inventory by the "Latest added" option. Later I noticed that all my gold was gone (around 8k at this time). First I thought I accidently lost it, but then I lost it again and after some more trying and investigating it was clearly reproducable. If interested, I might provide a savegame or something.
