Hi,

gnome-sudoku uses string exceptions, which have been deprecated for a long time and no longer work on Python >= 2.6:

From http://lists.debian.org/debian-python/2010/05/msg00113.html

$ python2.5 -c "raise 'eggs'"
-c:1: DeprecationWarning: raising a string exception is deprecated
Traceback (most recent call last):

+ Trace 222156

gnome-sudoku uses them in gnome-sudoku/src/lib/pausable.py:

    def wrapper (self, cls, *args, **kwargs):
        if cls.terminated:
            raise "Terminated!"
        while cls.paused:
            if cls.terminated:
                raise "Terminated!"
            time.sleep(self.sleep_for)
