[GNC] Advanced Portfolio: "sell transaction causing a negative stock balance, and a subsequent buy transaction causing a zero balance"

[Anthony Joseph Messina]

With GnuCash 3.1 on Fedora 28, I encounter the following error with the 
Advanced Portfolio report that I didn't receive on previous 2.6.y versions.

"There is an error processing the transaction 'buying 1.4907 share units'. 
This may to be caused by a sell transaction causing a negative stock balance, 
and a subsequent buy transaction causing a zero balance. This leads to a 
division-by-zero error. It can be fixed by preventing negative stock 
balances."

A stock in one of my 403(b) accounts was exchanged for another back on 
4/24/2015.

Date		Description	Tot Shares	Tot Buy	Tot Sell		Balance
4/09/15												258.9702
4/24/15	Transfer		-260.4609			38,540.22	-1.4907
4/24/15	Contrib		1.4907		220.58				0

What is the proper fix here?  It seems like the "Contrib" entry needs to be 
moved just before the "Transfer" on 4/24/15, but I'm not sure of the way to do 
this.  If I try to fake the date of "Contrib" to 4/23/15, I get the ominous 
warning about moving a transaction that's been reconciled, so I don't really 
want to do that.

Thanks for your help.  -A
