It seems the memory leak was due to a problem in Numpy git master (I've
yet to track down the root cause). Reverting to Numpy 1.6.1 resolves
the issue, though.
As for your bug, it seems there is a bug in how the plot_formats
commandline argument is parsed. Could you please try this branch an
I'm looking into this. It seems there's a pretty straightforward-to-fix
bug parsing the commandline arguments. Beyond that, though, there
appears to be a pretty serious (and relatively recent) memory leak in
the plot directive that's preventing my own runs from finishing. I will
let you know
