System Information
Win 7 x 64 ubuntu 13.10 x64 nvidia 560 - nvidia 460

Blender Version
Broken: 2.69 Date 2013-12-30 01:09 19103b4 (build bot win x64)
Worked: 2.68 at least

Short description of error

Turning on and off the simplify option (scene properties) crash blender if the dustcover mesh has an subdivision surface on it.
Note that the buttons, each of them, are parented to three vertex to follow the polygon face animation.

Exact steps for others to reproduce the error
1-select the dustcover (MRM_DELANTAL_HR)
2-add a subdivision surface modifier
3-turn on and off simplify until crash, it may take a few turn on and of to crash, repeat this step at least five times, also doing this wile playback the animation should crash it for sure

Blend file:
DOWNLOAD SAMPLE

NOTES: probably the problem isnt at the simplify, we also get crashes turning on and off the modifier and adding and removing a original solidify modifier that i took out to made a cleaner scene.
I remember that not long ago a commit was done on the vertex parents, i am sure that this model was done and the buttons parented before that commit, the scene was set with blender 2.67 - 68 cant remember.

thanks

I just download the file at home, it seams to be that the sample file has some linked geometry that its at the server at the office, ill fix the sample file on Thursday.
my bad sorry

geometry its missing but still crashes, just with the empty reference objects parented

Fixed File, but it seams that is the same with geometry or no the parent crashes the file, unfortunately i could not reproduce the error outside this mesh.

Caused by the threaded object update. Workaround would be to run blender from command line with -t 1 argument.
