Comment 9 for bug 1616842

I've tracked it down to r538 in qtmir [1]. The app startup improvement unfortunately also causes this crash. It's most likely a race in Qt, possibly fixed in later versions.

One workaround would be to not destroy the greeter when apps (currently only dialer) are launched over it (we only destroy it to save resources anyway).

Until that's possible we might need to revert this :/
