The program 'f-spot' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRequest (invalid request code or no such operation)'.
  (Details: serial 6642 error_code 1 request_code 156 minor_code 19)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

Program crashes after clicking on import or trying to open an image already in f-spot. Had only started using f-spot yesterday, imported and exported pictures. Soon as I try to use the f-spot today, it crashes as soon as I try to do anything.
