Unfortunately, that's not the problem. It still doesn't work after 
creating 11 or more particles.

I've been using position-dependent distribution of particles for months 
now in my own code, often with many contexts not containing any 
particles. The problem only arises when the number of contexts is 
getting too high (mostly 8-10 being the limit). However, I have no idea 
what triggers the error...
