Crash on import

[hsoft]

From GS

I tried to import my latest credit card and rather than seeing the transaction as usual I had an empty screen. Then I decided to swap the description/payee as I have to do it and got the following crash

The key to reproducing this bug is to obtain an empty import panel, which is supposed to be impossible. I'm asking additional info to the user.

I finally reproduced it. I created a QIF file with 2 empty account records, with one of them having a "D" line with a valid date (so that the _parse() phase think it's a valid file). Then we end up with an empty import window popping up.
