Could you try the following fix and report the result please? If  
successful (it works here) it can be applied to the AG svn repository  
so that future package releases will include it.

In the file /usr/lib/pymodules/python2.6/AccessGrid3/AccessGrid/ 
Toolkit.py, find the line
     os.environ['LANG'] = "C"
and replace it with
     locale.setlocale(locale.LC_ALL, 'C')

Please ensure that the indentation of the new line is the same as the  
deleted line.

At the beginning of this same file, just after:
     import socket
please add a new line with:
     import locale


Thanks to Marcelino for the suggested fix.
