[Discuss-gnuradio] X Window System error

Dear Sir,

I've just install gnuradio using pybombs, and manually install the missing python-opengl using apt-get.

Unfortunately below error occurs when I execute a flowgraph.

  Executing: "/home/sgku/Dropbox/gnuradio/gr-activecat/examples/jitter/top_block.py"

  Using Volk machine: avx_64_mmx

  The program 'python2' received an X Window System error.

  This probably reflects a bug in the program.

  The error was 'BadMatch (invalid parameter attributes)'.

    (Details: serial 2351 error_code 8 request_code 70 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.)

Please advise if you have a quick fix to this.

My system and version info is available at [1].

Thank you very much.
