I'm afraid you are right -- at the moment, the python interface only exposes
ParamValue(name,int), (name,float), and (name,string). It doesn't expose the
general (name, anything) constructor, so it's probably getting tripped up on
some compound object.
Maybe as a workaround, it would be easier to use ParamValueList.remove(name) to
just exclude the specific things you want to eliminate, rather than add one by
one everything else?
Also, if this is all you're doing from python, you could try from the command
line with oiiotool using the --eraseattrib command?
