OK.

OK.

The debug symbols package is only needed for the version installed with apt. 
You no longer need it as you've removed the gnuradio package and re-installed 
from source. Remove this debug symbols package as well.

When installing from source make sure you are building with debug symbols (-g, 
-g3 or -ggdb flags in CFLAGS and CXXFLAGS). Set CMAKE_BUILD_TYPE to 
RelWithDebInfo

 cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo ..

Then run

 make clean
 make VERBOSE=1 | grep "\-g"

and check that -g flag is present in the output. After the full rebuild you 
need to reinstall and hopefully this time the backtrace would contains some 
more information.

It could help.
