Since a while, i get crashes/segfaults upon exit, and they're fully reproducible now:

#_0  0x00000369644ca427 in QNetworkConfiguration::~QNetworkConfiguration () from /usr/local/lib/qt5/./libQt5Network.so.2.2

This is with master as of yesterday, qt 5.9.4, on OpenBSD. Just opening qgis, and exiting. Strange that the trace appeas to be only in Qt, i don't know what qgis codepaths lead to this

Guess i spoke too fast.. not 100% reproducible, but in this session i only opened a file open dialog then exited qgis.
