I fixed the freezes by disabling Versions in Mountain Lion for Omnigraffle. Seems as if by automatically saving a new versions also generates a Quick Preview that caused the Console errors and freezes.

defaults write $(osascript -e 'id of application "OmniGraffle"') ApplePersistence -bool no

Still I’d like to use OS X versions with large files. Please fix it.
