1131 :  error closing file <filename>

     Explanation:  It is likely that the file specified has been
     inadvertently deleted by another user on the system while Blinker was
     still using it, or there could be a network or disk failure.

     Action:  Make sure the file actually exists and that you have
     sufficient rights on the network.  if you are not on a network, make
     sure your disk is free of errors.
