[Bf-committers] Patch #3760 Regression in 2.44

[Ton Roosendaal]

Hi,

Yes that is a good test to add in Blender.

Note that this error only happens in rendering commands within the UI  
(not commandline), and with no 3D window present.

(BTW; if this takes you a couple of hours, you might consider to get  
help with gdb! NULL pointer errors always pop up as first, without any  
effort from developer side...)
