The recent Aperture installer has a problem, and your installation may be incomplete. You should remove your current Aperture application and reinstall, see this Apple support article on how to do that, depending on how you bought Aperture:
Aperture 3.4: May quit unexpectedly on launch after updating

Just in case you still should have crashes after reinstalling, post back, please.
