Re: flowgraph crashes when I enable a block

I also tried with python 3.8, also in conda.  Same problem.

I just tried with the latest commit, same issue.  Maybe its the python version?  I'm using 3.9.18 in conda.  This is the message I see, but I feel like these X errors aren't usually the actual problem:

(gnuradio-companion:1759026): Gdk-WARNING **: 06:23:29.883: The program 'gnuradio-companion' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 6258 error_code 11 request_code 131 (MIT-SHM) minor_code 5)
  (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.)

I'm using v3.10.2.0 from source, in conda.  I'll try with another version.

Just tested with a freesh build from main
and it works. I can enable the block and run the generated flowgraph.
