Bug#514781: sudoku: repeatable crash due to AssertionError

[Eric Cooper]

Package: gnome-games
Version: 1:2.24.2-1
Severity: normal

After solving a puzzle using multiple trackers, I got into a state
that I've reported before (#489822), where the program doesn't notice
that the puzzle is solved.  My usual workaround is to clear one
square, quit, restart sudoku, and then fill in the missing square.

But this time, I couldn't restart.  The presence of the saved game
causes the following error, before the window even appears.

  Traceback (most recent call last):
    File "/usr/games/gnome-sudoku", line 66, in <module>

    File "/var/lib/python-support/python2.5/gnome_sudoku/gnome_sudoku.py", line 21, in start_game

  AssertionError


I'm attaching the file
.sudoku/saved/005000000090805001108002040300001690906308402072600003060400908800206010000000300
which causes this crash.  I couldn't run gnome-sudoku until I had
removed it from .sudoku/saved/.

I notice the occurrence of None in the string that represents the
grid, when all the other elements are digits -- that looks like a bug.
And indeed, when I change that None to 0 with an editor, the program
starts up correctly.
