[GNC] GnuCash 3.7 crash in online banking

[Eric Haszlakiewicz]

I'm trying to get online banking set up with my Chase credit card, and
while using version 3.5 I tracked down a bug in what GnuCash was sending
that was causing things to not work (bad NEWFILEUID header, fwiw) , so I
decided to try with the newest version, 3.7, on Windows 10, hoping that the
bug has been fixed.
Unfortunately, the online banking now *always* crashes.
I've completely cleared out my aqbanking folder, and the steps to get it to
crash are:
* Tools->Online Banking Setup
* Click Next, Start aqbanking Wizard, then Create User
* Then click next, choose OFX-DirectConnect backend, next, and Run
* In the OFX DirectConnect Setup Wizard, click Next, then select the bank:
"Chase(credit card)  (636)", Next again
* The values for user name, user id and client uid don't seem to make a
difference, fill in something, click Next
* The emulated application doesn't seem to make a difference, use default,
click Next
* Windows pops up asking to accept certificate, click Yes
* GnuCash crashes. :(

When I start it again, I can't even delete the aqbanking user because it
tries to acquire a lock and fails with error -109, so I need to remove the
aqbanking folder again.  If I remove just the *lck* files, I can get it to
crash by clicking the "Retrieve Account List" button inside the online
banking setup.

Is anyone else having this problem?  Any possible fixes or workarounds?

Thanks,
Eric
