Hi Ton, hi Blenderixx ! ;)
Sorry for using this way to submit a patch for fixing a bug in
blender, but my problem to log into the bugtracker or into the
www.blender.org still remain. I dont know whether this is due to
a bug in my browser, in my proxy, in my firewall or ... ???
Recent snapshots of blender (cvs) do crash if the material buttons
are entered, while an object is active, which has no material or
while the material buttons are active while switching to an object
with no material.
I found a way to avoid this crashing. Be warned! This are my first
steps into the blender source! The only thing I can say is:
For me it works.... ;)
here is the patch :
