Hello Breno Lou,
the errorlog you posted shows, that Aperture crashes with a very typical error message: Do you have by any chance installed "Final Cut" lately? The error message is, that a Framework is missing in your system library:
/Library/Frameworks/PluginManager.framework/Versions/B/PluginManager
Open your System Library by using the Finder "GO" menu:
Finder -> Go -> Go to Folder and enter: /Library/Frameworks
Then browse this folder and see, of the framework really is missing.
If that is really the case, either try to restore this Framework from your TimeMachine Backup or reinstall the Operating System - this should restore the framework.
Post back, if you need further assistance
Regards
Léonie
