When unlock phone, password keyboard disappears

[jtd]

Ubuntu phone 15.04 (r24) [mako]

This was first noticed during r23, still present on r24.

Bug: Phone is suddenly slow on password entry to unlock phone.

Expected behavior:
(1) Unlock phone: I tap on/off button to unlock phone, swipe right-to-left, enter password on keyboard, hit enter, unlock phone Cannot complete password to unlock phone without keyboard disappearing, requires extra tap on screen to bring keyboard back and continue password

Actual behavior:
(1) Unlock phone: I tap on/off button to unlock phone, swipe right-to-left, enter password on keyboard, keyboard disappears before password complete, must tap screen once more to view keyboard again and finish password to unlock phone

Any chance you could enable error reporting in Settings app, clear /var/crash/* and ~/.cache/upstart/*, try your steps again and see what shows up in the two directories?
