hi guys i'm getting a 'Couldn't create output file .xdebug_tkmedit' before loading volumes, any suggestions on what I can do would be most welcome. Also got:

ERROR: A segfault has occurred. This is not your fault,
  : but is most likely an unrecoverable error and has
  : made the program unstable.
  :
  : Please send the contents of the file .xdebug_tkmedit
  : that should be in this directory to freesurfer@nmr.mgh.harvard.edu
  :
  : Now exiting...
  :

When taking a volume snapshot and then freesurfer shut down but there's no file for me to send you, I've just installed on a mac lion v5.3.0 

Cheers!
