Hi Jason,

I tried to but could not reproduce the issue on latest testing.

Could you please give it a try again?

I ran:
mkdir /tmp/fake-home meld
cp .Xauthority /tmp/fake-home/
HOME=/tmp/fake-home meld

but got no traceback.

Cheers,
Balint

I think this could be closed Resolved?  I have "important" added to my
"AptListbugs::Severities" and warned before installing meld.  No issues
here running /usr/bin/meld 3.22.0-2 with Python 3.11 from stable repo.
