[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

[Gaia]

i got a .blend file from a customer but i can not use that within a bug 
report.
The only hints i have so far:

1.) right after the (rigged) object enters weight Paint mode, i can see 
in the debugger:

me->totselect = 1
me->mselect = NULL
one vertex has the select flag enabled.

2.) The problem raises when the customer does:

- open the .blend file (now we are in Object mode)
- set the armature to pose mode (works)
- select the object (works)
- enter Weight Paint mode -> Crash at the location i commented

I still try to find a simple example to create a bug report for this,
because i suspect the true cause is somewhere else.
But so far i could not recreate a blend file having this problem.
I am still looking at this and try to find out how the customer got
into this state.
