[GNC] Delete a trading account => crash

[Fred Tydeman]

Running GnuCash 4.14 on Fedora Linux.

Due to a mistake on my part, I have two Trading accounts:
  IVR-PC
  IVRPRC
for the same security.

First, I tried changing Trading:IVRPRC to Trading:IVR-PC in a Sell or Buy
transaction from the cash account. However, when I pressed Enter,
Gnucash undid my change.

Then, I tried deleting Trading:IVRPRC account and moving its transactions
to Trading: IVR-PC.
That crashed Gnucash.

I am now running a Check & Repair all (takes many minutes).
