I could not reproduce the segmentation fault on a fresh installation of Debian jessie with xfce4 under VirtualBox. I could switch virtual desktops during a call without any issues. Interestingly, twinkle complains about the missing DRI driver: libGL error: pci id for fd 21: 80ee:beef, driver (null) libGL error: core dri or dri2 extension not found libGL error: failed to load driver: vboxvideo > Possibly affected/DRI-bug injecting packages libqt5network5 libqt5qml5 > libqt5quick5 qml-module-qtquick2 I will forward this bug to the Qt maintainers.
