I just imported a small Outliner file in OmniGraffle but when I attempt to save, I get this error:

The document “Untitled” could not be saved as “Untitled”. -
[NSConcreteAttributedString getCharacters:range:]: unrecognized selector 
sent to instance 0x1adc5040

Another error occurs occasionally, maybe every 2 minutes, as I mouse around, click on objects but otherwise not making any changes:

Alert

-[NSConcreteAttributedString stringByTrimmingCharactersInSet:]: 
unrecognized selector sent to instance 0x165dda70

This is a bit of a show-stopper so far. It is in my first couple hours of demo'ing version
