I can reproduce and therefore confirm that.

Yep, that's when I occassionally run into this issue, too, during
daily use. But it never caused harm and I just noticed it
accidentially once or twice, when looking at the process list for

... also in the new upstream version I uploaded yesterday. Not sure if

help either.

Ok, this is annoying. I though never ran into this variant myself.

Sad, but understandable.
