BTW, ngfd tag 1.4.5 behaves the same. I’m looking at a C2 device.
I can see two different segfaults, sometimes it’s one, sometimes the other. I also have seen a SIGBUS error instead of the segfault, but can’t reproduce that one.
Backtrace after issuing:
busctl --quiet call com.nokia.NonGraphicFeedback1.Backend / com.nokia.NonGraphicFeedback1 Play 'sa(sv)' email 0

Aha, finally got the BUS Error as well. Run with -vvvvvvvv. Note the garbage at request->name!
