[Yt-dev] new comm problem

[Sam Skillman]

Hi Stephen,

It looks like the other derived camera classes that were overwriting
__init__ didn't have the ParallelAnalysisInterface initialization, which has
now been fixed in:
https://bitbucket.org/yt_analysis/yt/changeset/510d1815e9af/

Basically you have to send "self" to the PAI __init__() function, as you'll
see in the diff on that changeset.

Hope that helps.

Sam
