Bug Description
With kernel 4.4.0-119-generic on Ubuntu 16.04.4 LTS (xenial) x86_64 and included intel_hid driver (which seems to be responsible for the key events), I get the following report when pressing the function key Fn+PrtScr which is supposed to trigger the wifi blocking state using rfkill interface via urfkilld daemon:
Apr 17 19:02:45 aton kernel: [ 387.963583] urfkilld[3119]: segfault at 18 ip 000055948349f46b sp 00007ffd26296730 error 4 in urfkilld[

It seem that urfkilld crashes and gets restarted by systemd or similar. Nothing happens to the Wifi button state which can be shown via
rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
Another oddity is that the urfkill package in all Ubuntu versions is
0.6.0~20150318.
but upstream websites have
0.3.0 (https:/
0.5.0 (https:/
only. Seems like almost abandoned software to me.
Since this was a distribution upgrade, I purged and reinstalled the package but without effect.
Any ideas?

On my notebook, urfkill dumped core while starting the GUI causing it to loop in the GUI initialization, so I simply removed urfkill and did not install it again. I never missed that bugger ever since... (FWIW)
