I've packaged the patch you pointed out for this issue, and uploaded it
to a PPA for your testing convenience:


If you're interested, this may qualify to be accepted as a Stable
Release Update for all focal and bionic Ubuntu users, however in that
case we need your help.

We don't know how to reproduce the issue you experienced, based on what
was discussed upstream.  We either need your assistance to help identify
how to reproduce the problem, or we need you to handle the validation
(both now, against the PPA, and again later for final verificaiton when
it's been accepted for the archive).  If you're able to do either of
these, please join the bug report Christian filed for it and let us

Thanks ahead of time,
