The program 'emerillon' received an X Window System error

[Fabio]

I've got the following message trying to open Emerillon 0.1.90-1build1 from terminal in Ubuntu 12.04. I've installed it by terminal:

(emerillon:2257): Gdk-ERROR **: The program 'emerillon' 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 125 error_code 1 request_code 154 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 GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
