Still lots of warnings during startup on Linux

[terrillmoore]

Tested 2.7.0 on Linux (Ubuntu 20 LTS/XFCE and Ubuntu 22/standard desktop).

Still too many errors.

On 20:

Note the assertion failure. Warnings need to be eliminated (by correcting the problems) so that we can see errors.

Note the assertion failures.

Please fix these before next ship.
