Hmm ... I guess there must be some other bug then ...
I think you need to run under gdb and go back up a few stackframes after the 
and see what the cString_u function thinks the current default cString encoding 
This should only be happening if the strings you are using (in this case 
contain characters that can't be represented in the current encoding - but it 
may be
that either there is some bug that is stopping the encoding being set 
correctly, or
there is a bug in the unicode->cString conversion.  I don't think I can tell 
you can give me some way to replicate your setup perfectly, and run under gdb
