Comment 4 for bug 1930121

Tanks Grant for spotting this!
Thereby I'll set this one to confirmed (while it isn't an issue of the PKG in the archive you said we might be able to help with it still).

We have three more bugs that might be the same, but their report didn't include the python3 details that made you spot it here. I've asked on those bugs to check and making them a dup of this one here if they indeed have custom python3 on the systems:
 - bug 1927348
 - bug 1927905
 - bug 1934077
