    I had this bug in the GM and it went away, but today it came back, on both a 10.11.1b MacBookPro and a 10.11.0 desktop. Mail will crash within a minute of launching. The error is:
    *** Terminating app due to exception while holding database lock 'NSInternalInconsistencyException', reason: 'Cannot set MFGmailLabelStore as data source for message.'
    abort() called

    Quit Mail
    In your User's Library/Containers folder, drag folder to the Desktop.
    Log out/in
    Open Mail and see if problem goes away.

    If no, then test in a new User. Testing in a new User will quickly tell you if the problem is system wide or if it's your User's folder that contains the problem.
