Short description of error
Linked libraries+Cloth objects+LineArt -> Blender crashes

I'm in kind complex project. There're characters (roughly meshed, and bad rigged, but working), with 'clothed' hair, and all of them LineArted.
Many of the scene files work ok, so they've not much characters. But I don't know why, some of them can't render more of a bunch of frames, even they crash when calculating something (i don't know if's about either cloth, collisions or LineArt modifiers, or whatever.
Memory looks ok, a little is used.
I attach both files: a scene, and the characters source (personajes.blend).

Load 's4 pl1 coleAna.blend'
Just 'Play' and wait.

For me, it crashes after 5 frames or so.

A simpler backtrace:

Seems to be a threading issue in lineart (or at least triggered by lineart).
For me, starting blender from the commandline with --threads 1 gets rid of the crash
