This is introduced by a work around for another bug. The only way to save the hint-data for a double in the end of a match (or saved position) is to add the double to the match. Not the best way to solve the problem, but I didn't want to mess with the sgf data format. Keep that in mind if you change anything.

With an up-to-date CVS snapshot:

Start a new match (7-point with Crawford rule enabled). After three complete moves without doubling go to Analyse->Analyse match or session.

The progress bar in the bottom right corner will stop at 2/4 (50%). Save the match to a file and reopen it. For the player on turn a double was saved in the file although that never happened.

I originally came across the bug, when saving and loading a match a couple of times. At one point the resulting SGF file ended with two subsequent doubles of the same player. I cannot reproduce that exact behavior though.
