Bug description:
[Impact]
Certain code paths may cause the Unity lockscreen to crash, which can
allow the screen to be unlocked without a password entry.
[Test Case]
Unfortunately this bug only appears under certain race conditions and
is not reliably reproduce able.
[Regression Potential]
The change in the code simply assumes that if a screen is already
locked, then it is lockable this avoiding certain operations that are
inherently racy. It is possible that this fix does not avoid all
possible crash conditions in the lockscreen and there may still be
unaccounted-for crashes in the lockscreen.
[Other Info]
This fix was cherry picked for Ubuntu 14.04 LTS from the Ubuntu "Vivid
Vervet" dev release where it has been in testing for some time.
