Just an FYI to any others using ‘TuncatedTime’ CMD line setting as follows totally hoses OF2 at the moment.
defaults write com.omnigroup.OmniFocus2 RelativeDateFormatterDefaultWantsTruncatedTime YES
( as per un-official settings mentioned in thread here for OF1 http://forums.omnigroup.com/showthread.php?t=19114)
If set opens blank/unresponsive/force quit etc since build OmniFocus-2-r207818 from about a week or so back - ok before that + note: other settings in old thread still seem to be working ok.
Took me few days til I tracked down the issue.
