I'm on Ubunutu 9.10, relatively fresh install, i32 P4. I have never even run F-spot until I tried a few minutes ago. It began to open and immediately crashed. I tried at command line with these errors:

(/usr/lib/f-spot/f-spot.exe:10605): GdkPixbuf-WARNING **: GdkPixbufLoader finalized without calling gdk_pixbuf_loader_close() - this is not allowed. You must explicitly end the data stream to the loader before dropping the last reference.
The program '/usr/lib/f-spot/f-spot.exe' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 2962 error_code 11 request_code 53 minor_code 0)
  (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.)
