thanks for the report. 

Marco, the .sgf-file has AP[Goban:3.2.1 (v65.1)] in the header, I assume
this is Sente Goban? The .sgf-file doesn't make sense, there is a move
at an occupied position (White at B2).  
There are other moves that don't make sense; I am pretty sure that Goban
and GNU Go disagree on the actual board position. Of course, the bug may
be on either side.

Earlier there apparently was an undo (Black H8), something which is known
to have caused trouble for pretty much any go-related program...
