[gnugo-devel] Worth a test case?

[SP LEE]

It's to me still a lot of fun playing with gnugo. This time I've found a 
blunder of it that I didn't quite understand. The game record is attached.

Of course the results could be alive, dead, seki or ko, depending on the 
move sequence. However, gnugo gave up the chance to make a seki in the end 
and let it dead.
