[Bf-committers] Patch #3760 Regression in 2.44

[Early Ehlinger]

Hi Ton,

Actually, this was only rearing its head from a python-invoked render 
from a command line.

Took this long more because of the environment - couldn't run inside of 
a debugger, because for some reason the bug disappeared :-)
