The error is in your own method GetDriverByName. I have no idea what this method does.
It is very strange though that it reports a TypeError containing what seems to be part
of a C-language error ("char const *").

That remains to be seen :-)
Does the GetDriverByName method work without using Pyro? If so, what arguments are you
passing into it? In what way do they differ from the call via Pyro?

I don't know what you mean by "only the first is read". It does sounds like a problem in
"the class", not with Pyro (Pyro just passes on the parameters it receives)

Try simplifying the issue. Call "the class" / GetDriverByName directly. Enable
logging/debug print statements. Print the full Pyro traceback instead of just the simple
TypeError. Set a breakpoint in the offending code and see what arguments are passed in.
A lot of possibilities, without seeing actual code that manifests your problem it is
hard to say.
