Strange message from a program

[Damien Touraine]

Hi,

We use Python 3.2 on standard Ubuntu precise Linux.

I have a big program with several dependencies (mainly PySide). But, 
sometimes, it fails with :RuntimeError: Can't find converter for 
'\ufffd\ufffd' to call Python meta method. The given string 
('\ufffd\ufffd') is changing each time. Moreover, it can make a 
segmentation fault, but not each time it fails.

I don't even know where this can of error can occur. I have searched for 
this string in the program and none exists.

Can you tell me the cases when search message appears ?

Regards,
Damien Touraine
