[Bf-committers] Re: [Bf-blender-cvs] CVS commit: blender/source/blender/src buttons_object.c

Hi Zr, Jms's fix from everything crashes blender.
Make a box, subserf it and then run fix from everything (in python menu, 
mesh edit mode)

- Heres the crash

Program received signal SIGSEGV, Segmentation fault.
