Comment 1 Justin Zobel 2020-12-07 04:31:11 UTC

Thank you for the report, Bauke.

As it has been a while since this was reported, can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved.

I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved/worksforme" when you respond, thank you.

Comment 2 Bauke 2020-12-07 20:05:34 UTC

It's not reproducible afaik, so unless the stack trace points to an obvious issue, there's little that can be done about this.
