[fixed] history crash

[ircarrascal]

When you open the history ("H") there are two sets of arrows: one to browse the different divisions and the other one for seasons.

When you try to circle around the leagues, for example going from 1 to 2 to 3 ... and then back to 1 (or to be more precise, the summary page), Bygfoot crashes (happens when going back to summary page, works fine between divs). The error message on the terminal is:

Segmentation fault (core dumped)

Could you send me a savegame? (An SVN version savegam, if possible.) I don't have season-long games myself.
