backtrace

Version:           4.5.3 (using KDE 4.6.2) 
OS:                Linux

I just loaded an OFX file for my credit card.  The payment was automatically matched to an account I used to use to pay this card.  I right clicked on that transaction, and in the ledger for the old payment account, I moved the transaction to the correct payment account.  I then returned to the home window and reselected the credit card account.  As soon as I click on the payment transaction, KMM crashes.  I have tried this three times.  (I did a backup so could get an anon file if necessary.)  Just editing the transaction and changing the "from" transfer account works fine.

Reproducible: Always

Steps to Reproduce:
as above in details

Actual Results:  
crash

Expected Results:  
should be able to edit account

Yes - just changing the payment account while editing the transaction in the credit card ledger is easier, but I think what I tried should work.  I wonder if moving the transaction didn't get the other end updated correctly, so the transaction still in the credit card account became invalid somehow?
