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', 
   '*** -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!

  • System gives back: 2013-10-23 17:57:44.610 defaults[781:507] Domain (com.apple.mail) not found. Defaults have not been changed.

Open Terminal.app (under /Applications/Utilities) and run

defaults delete com.apple.mail ColorQuoterColorList
  • So mail.app will crash under Mavericks if you changed the default colors for "Fonts & Colors" > "Color quoted text" in a previous version of Mac OS X?

  • @Blaise: I'm not sure that's all it takes, but I don't recall doing anything else so — apparently yes.
