Code review comment for lp:~widelands-dev/widelands/i18nfixes

I get the crash again - on different place - single player, in screen 'Launch game', I hit 'back' and got the same crash, backtrace points again to:

.....checkbox.h:51
51 bool get_state() const {return m_flags & Is_Checked;}

I am completely unfamiliar to this code.... no, I dont feel like digging into this problem...
