Comment 35 for bug 1387219

Emilien Klein, I did what you did, but this does not solve anything.

I get this error too, but perhaps this debug message will help to isolate and solve the problem:

con@laptop:~/Documents/Simmons/CPF1409004/Bamfiles$
(gedit:6804): Gdk-ERROR **: The program 'gedit' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadLength (poly request too large or internal Xlib length erro'.
  (Details: serial 8426980 error_code 16 request_code 18 (core protocol) 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 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.)
