Exception during region border crossing

Sporadically During region border crossing my avatar gets the message hat he had just paid everything he has, and his balance drops to 0. After the next crossing his balance is automagically restored.

In the Console I see this error when thi happens:

2012-04-24 21:20:49,996 ERROR - OpenSim.Data.MySQL.MySQLMoneyDataWrapper.MySQLMoneyManager Error updating transation in DB: System.InvalidOperationException: Connection must be valid and open.
