[GNC] 3.4 upgraded, crashes when paying invoice

[Rich Shepard]

Environment: Slackware-14.2, Gnucash-3.4.

Upgraded over the weekend by removing -3.3, building and installing -3.4.
The new version appeared to be working.

This morning I entered and posted a vendor invoice and tried to pay it from
the business' checking account. After filling in the dialog box with the
payment due date, amount, check number, and activating the print check
checkbox, I cliked the 'Print' button. Gnucash immediately shut down.

Tried twice; same results both times.

The log file, business.gnucash.20190128100724.log (redacted) shows this:

mod     trans_guid      split_guid      time_now        date_entered    date_posted     acc_guid        acc_name        num     description     notes
    memo    action  reconciled      amount  value   date_reconciled

I need to have gnucash working ASAP. What other information can I provide?
