[Paraview] Stream tracer with custom source fails in parallel mode

Fri Mar 18 10:03:32 EDT 2016

Hi Lukasz,

I was able to replicate your crash in your first parallel crash with PV
5.0. I didn't try any of the other cases yet but am guessing that they're
all related.

Thanks for the bug report.

Best,
Andy
