I hope my information is complete enough without being too verbose...

Lvl1 Hill Dwarf Tinker Dropping Leather Apron [+0,+1] (80s) (with intent to sell) with Unpurchased Woolen Loincloth [+3,+0] (20s) in inventory generates error message. Shopkeeper is a Mountain Dwarf. Shop contains various weapons and armor and a couple scrolls of identify. 566 moves into the game. Never been in combat.

*Update: Continued from the error message, and never got my gold, but still lost the apron (it's not even on the ground)! :(

I don't know every factor that should be listed, but since the error message was generated by attempting to sell something and at the time I had an unpurchased item, I figured that could be the issue.

If more information is needed, please contact me.

A controlled JADE error occurred.
Please see the stack trace for details.
