How did you install gnuradio previously and how did you uninstall it? Make sure 
you don't have two gnuradio versions installed in parallel - one from deb/apt 
packages in /usr and a second one from source in /usr/local.

Why 3.10.4.0 and not the latest 3.10 (currently is 3.10.5.1)?

How did you install the debug symbols? Before or after installing from source?

We don't need python debug symbols as this segfault is not in the python and we 
are not going to debug the python executable.

That's strange. Is this with gnuradio installed from source?
