[Bf-python] bug checking before 2.37 release

[Ken Hughes]

I've got some spare time so I can look some of the open reports
in the bug tracker.  If I find things I'll post comments on the
bug tracker and summarize here (will that help, Willian and Stephen?)

I looked into this one:
   https://projects.blender.org/tracker/index.php?func=detail&aid=2490&group_id=9&atid=125
and don't think it's a bug, just some unnecessary warning messages.
