ERROR: PL/Python functions cannot accept type record
Ugh, yeah... that won't work. plperl might be able to do it, but I suspect you're going to be stuck pulling the size info out of info_schema or the catalog.
Actually, there is a way you could hack this via plpython; pass the row in as text as well as the relation (regclass is good for that). You could then do plpy.execute('SELECT (%::%).*'.format(row_text, relation)); that should give you a dict just like Adrian's example did.
It would be nice if there was a function that accepted something with a row descriptor and spit out the details of the descriptor. http://pgxn.org/dist/colnames/doc/colnames.html comes close; if you know much about C at all it shouldn't be hard to add a function to that extension that returned the full details of the row. That and converting the row to JSON would make it relatively easy to accomplish what you want in a plpgsql (or maybe even plsql) function.
