Crash on Transaction deletion

I am in the midst of converting from Quicken to KMyMoney.
The system is not recognizing duplicates resulting from split 
transactions (I understand and actually expected this).
But this requires me to delete a number of transactions after importing 
them.
Suddenly about half way through the process multiple deletions cause 
KMyMoney to crash. The windows message is not very informative.
Very rarely it seems to crash on a single deletion, but this may be a 
cumulative event. I have tried deleting them one at a time, it works for 
a while before crashing.

Any suggestions? I suspect it may have something to do with file size 
because it did not crash until about half way through the import 
process. I am importing one account at a time.
My first attempt was to import the entire Quicken file, but that 
resulting in chaos, so I created a new file and started over.

*.kmy file is only about 1.5mb at this time.
