Here is the problem with the .sgf file:

The third quoted line tries to place a black stone over another one which
has just been played. Actually, this file is only "bad style" according to
SGF specification, but we find it easier to treat such files as erroneous.
You may delete the AB[] tag. This will make GNU Go happy and won't change
the actual contents of the file.
