[LyX/master] When catching exception, give error on STDERR

    When catching exception, give error on STDERR
    
    The error is reported in the GUI, but for the terminal we must write
    explicitly to STDERR.
    
    For a specific example of this type of exception, see the previous
    commit, 72c3dbd.
