[Bf-committers] [Bf-blender-cvs] SVN commit: /data/svn/bf-blender [57871] trunk/blender/source/blender/ blenkernel/intern/mesh.c: fixed Blender crash, but unclear when this situation can happen

[Brecht Van Lommel]

Is there any more information you have about this, like a bug report
or a description of when this happens? Now it's adding an XXX comment
but there's no information for someone who might want to fix the
actual bug.
