You can't run this test under valgrind like this. You need to open 
./build/gr-qtgui/python/qtgui/qa_qtgui_test.sh and on the last line add 
valgrind in front of python3. Something like:

    valgrind /usr/bin/python3 -B 
/Applications/gnuradio/gr-qtgui/python/qtgui/qa_qtgui.py 

Similarly you can run it under gdb in order to get a full backtrace of this 
segfault.

Regards,
Vasil
