Yeah. But not to LoadPlugin, but to the Parse-method of parser (which
is a vtkSMXMLParser-object). And that is a method that I'm not calling
myself.

    JMF> Please try again using the following syntax:

    JMF> LoadPlugin("yourlibname.so", ns=globals())

Gives the same error.

Good hint anyway, I'd probably have searched for the missing reader
once the above problem is solved ;)
