Short description of error
Crash happens on rendering (Cycles or Internal)

It has to do with having 2 particle systems with mballs, 1 in a hidden layer. That's as far as I could get.

Exact steps for others to reproduce the error

When I open the attached blend file and push F12, blender crashes.
But blender does not crash when I render it after updating cache of 2 particle systems.

Note that this bug is quite old (tested back to 2.61 - it crashes there too).

Linked to a diff for a suggested fix,
It changes metaball logic to only take visible layers into account, @Daniel Salazar (zanqdo) - does this seem like expected/acceptable behavior?

@Campbell Barton (campbellbarton) hi Campbell, why woudn't it be an acceptable fix? Does it somehow change how things work right now at an user level perspective?

blender 2.69 worked without crash.
