[GNC] Canceling QIF Import Erases ALL Transactions

[Eric H. Bowen]

Yesterday I ran into this...I was attempting a .QIF import of 
transactions from my credit card company. The import seemed to progress 
normally, up until the "Match Transactions" stage. When it got there, 
every single one of the transactions which I had entered over the past 
2+ years appeared in the list. I hit the cancel button in the requester, 
got the "busy" icon...and when Gnucash resumed, about ten minutes later, 
every one of my transactions in every account had vanished (with the 
sole exceptions of customer invoices and vendor bills)!

I did have a fairly recent backup file available, so I restored to that 
and tried the import again. The same thing happened a second time.

My NAS keeps track of file history and automatically saves the most 
recent versions every twenty minutes or so, so I do have versions from 
before and after the failed import saved (to a new file under a new 
name) as well as all of my log files. At the time of the import I was 
running Build ID: 3.8b+(2019-12-29) on Ubuntu 18.04.4 LTS in a homebuilt 
machine with AMD FX-4100 CPU, 8 GB RAM, and an ASUS M5A88-M motherboard 
and using the SQLite3 backend.

I opened a Bugzilla account and reported this (Bug 797651), but as 
reconstructing this may mean sharing my personal financial data I 
restricted the view access to the developer list. I have reconstructed 
my working account file from my backup, so there's been no loss of 
critical data. I'm sharing this for visibility and to ask if there is 
any additional information I should provide in the bug report to 
facilitate a permanent resolution to this problem. Thanks for any 
advice----Eric.
