No voice on gyach
 

Hi all, I'm using gyach on Fedora Core 3. After some sonfiguration issues it works well, but when I try to use pY! voice chat nothing happens, I started gyach from the console to see what happened and when I try to start pY! voice chat this is what I get:

/usr/lib/python2.3/ihooks.py:172: RuntimeWarning: Python C API version mismatchfor module pytspc: This Python has API version 1012, module pytspc has version 1011.

TypeError: flag values must be strings, ints or tuples

Does anyone know how to solve this problem and get voice chat working??
Help in advance.
