About 2/3 of the time, when I try to sell cargo from the 'mini unload/sell' window in the station's welcome tab I get a lua error.

vo/if_newstation.lua:126: attempt to read undeclared variable itemname
stack traceback:
[C]: in function 'error'
vo/vo.lua:251:in function <vo/vo.lua:246>
vo/if_newstation.lua:126: in function 'complete_cb'
vo/vo_ge_station.lua:222: in function <vo/vo_ge_station.lua:216>

vo/vo_ge_station.lua:319: in function 'StationUpdateMoney'
vo/vo_gameevent.lua:319: in function 'func'
vo/vo_gameevent.lua:989: in function 'GameEvent'

I doesn't seem to do this from the Load/Unload tab.

Yeah, it's a bug that I fixed. we'll try to get an update out tonight, else it'll be in the next regular update for sure.
