The traceback.print_exc gives:
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe4' in 
position 1: ordinal not in range(128)
print u'\xe4' correctly shows the German a-umlaut

I made a small PyQt4 test prog with a painTextEdit that shows the 
character correctly, both when started directly and as a subprocess. 
Sometimes I think I understood the in and outs of unicode and sometimes 
I think I am getting mad of unicode and (Qt) python.

Any suggestions where to look?
Thanks, Janwillem
