           Summary: Generated killer sudoku puzzle with multiple valid
                    solutions (ksudoku 1.3)

Screenshot showing the three-solution puzzle.

I've encountered a "killer sudoku" puzzle at the "unlimited" difficulty setting
that appears to have three solutions instead of just one.  A screenshot is
attached.  "Show Errors" is on, so the already-marked boxes are correct
(according to both me and ksudoku).  In the 18-cage in the upper-right corner,
'7' can be in any of three boxes, and each leads to a valid solution.  Ksudoku
incorrectly considers just one of these three solutions to be valid.  (Please
forgive me if I'm wrong and am wasting your time.)
