Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Hi, I report this bug in BF Blender as it seems to concern BF Blender too (not only upbge).
Sometimes it seems possible that we have a MTex with a null tex inside and in some functions we have things like if (mtex && mtex->tex->type == ...) -> This causes a crash because tex is sometimes NULL.
Test file: http://pasteall.org/blend/index.php?id=43764
Steps to reproduce the crash: check GLSL shading mode
Fix proposed (it was in upbge):

Thanks for your attention! Bye!

@MikeErwin, @brecht : Do you agree with this fix ?
Yes that should (and reportedly does) prevent a NULL dereference.
Small thing: would like parentheses around (mtex->tex->type & TEX_IMAGE) for clarity / readability
Fix looks good to me.
Changed status from 'Open' to: 'Resolved'
@MikeErwin : The () are added and the fix is commited in
