Bug description:
Confirmed on two devices, stopped happening after a reflash, need to
keep an eye out.
Quite uninteresting trace Albert managed to catch:
https://paste.ubuntu.com/23088259/
Steps:
* have a passcode/password-locked phone
* make sure dialer isn't running
* slide the greeter away
* tap on the "emergency call" button
Expected:
* emergency dialer opens
Current:
* unity8 crash
