When I click or double click on any message in the messages list on any account in Mail in Mavericks (10.9), Mail crashes immediately with the error
Application Specific Information: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -redComponent not valid for the NSColor NSCalibratedWhiteColorSpace 0 1; need to first convert colorspace.' abort() called terminating with uncaught exception of type NSException
What can I do to prevent this crash? I can't read any of my mail!
