[GNC] v5.3 split transaction auto completion not working

[Martin Neumann]

Hello,
I just installed v5.3 and encounter a problem with split transactions.
In the past on split transaction entries in the past prior used entries 
were auto completed, which now does not anymore happen.
I used this a lot to call up the correct account for the transaction 
based on it's description.

On normal "non splitted" transaction entries the autocomplete works as 
documented.

Am I doing something wrong?
Is this feature removed?
Is it a "bug"?

If anyone could help it will be much appreciated.
Thanks
Martin
