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.
