Running GRC files give following error after re-installation and update  
with gr-extras.

Using Volk machine: sse4\_2\_32\_orc  
The program ‘python2.7’ received an X Window System error.  
This probably reflects a bug in the program.  
The error was ‘BadDrawable (invalid Pixmap or Window parameter)’.  
(Details: serial 958 error\_code 9 request\_code 137 minor\_code 8)  
(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

This is definitely not a volk error. Can you say what application you  
tried to run that caused the error?

I’ve seen this on an older Ubuntu with newish GR code.

_ANY_ flow-graph using wxGUI falls over with this error.

Is it perhaps gl canvas related (I heard murmurs that there was a  
initialization issue from a previous OSX fix)? If you turn off the gl  
stuff does it start working?
