Jumping in hastily:

It seems to me that Ed faces a larger problem if the above scenario turns
out to be a viable attack. Consider the following sequence: Alice and
Charlie decide to get some (payee-anonymous) currency laundromat in hot 
water. Alice (payer-anonymously) washes some coins at the laundromat.
Con-man Charlie claims he didn't get paid for some fictional transaction with
Alice. Alice complains to the bank, and the rest proceeds as before. The
Alice-frames-Ed situation is functionally equivalent to the Bob-robs-Charlie
situation from the bank's perspective.
