Description

System Information
Linux 64, 32GB RAM

Blender Version
Broken: 40b2e75

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?
