main menu option comes up instead of context specific menu

Binary package hint: singularity

New game -> Easy -> Skip -> New Base
about half the time brings up the main menu option (Save Game, Load Game, etc)

An exception is also thrown :

Description: Ubuntu Natty (development branch)
Release: 11.04

Usually if I can get past the first screen related to making a new 'base', I can do so for the rest of the game.
Seems to also be a problem in other languages, other resolutions...but it seems like enough fiddling with the options and it eventually goes away.
