This makes sense to me.  It's a bug that you have a Bank account with
a Security different from the account's Currency; you can't (or
shouldn't be able to) create that scenario in the current GUI.  You
should change the type of Treas MM to be mutual fund or stock.

Were there any other problems in import correctness?
