Lion Preview.app crashes every time i use a key command

Question

Whenever I use a key command in Preview.app it crashes.
I'm fine selecting any command from the actual menus, but as soon as I use the key commands for the same functions the app crashes.
(And we're talking also basic stuff like command N or O or even Period to exit an Open dialog.)
So … anyone have any ideas?
I've tried trashing all Preview preferences in my library folder, and I've repaired permissions, and I've tried a safe boot … but the problem remains.
The problem is local, and everything works just fine for other user accounts on the same machine. But I'd rather solve the issue than migrating all my data to a new account.

Ha! Fixed it!
Kept reading all "Preview+plist" threads and found this one: https://discussions.apple.com/message/17195650#17195650
And sure enough, trashing ~/Library/Containers/com.apple.Preview/ reset the preferences for Preview.app and now all key commands work without crashing.
But if erasing that folder, and more importantly the plist in it, did reset the preferences, that would suggest the preferences were being saved there. So I now changed the prefs and quit the app, and then trashed the containers folder again, and restarted the app. But strangely the prefs remained. So I thought, well if the prefs were being stored there, maybe erasing that plist made Preview reinstate the regular plist in the regular Preferences folder? But no go, as there's still no regular Preview plist in the regular Preferences folder.
So now, there's no regular plist, and erasing the Containers folder no longer resets the prefs, but changes to prefs are still being saved somewhere … so where the **** are they being saved now? It's like they just keep burrowing down further into the ground with every attempt to erase them. What the **** is going on? ;-)
Anyways, the initial problem is solved, so … maybe I should just let the mystery remain? ;-)
