Comment 2 for bug 116883

It's version 0.9, installed from the package on the jokosher website. I'm running AMD64, but I had the same problem with earlier versions of jokosher when I was running i386.
The full error is:

The program 'jokosher' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 12823 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.)
