(Get the code!)
current build number: 127
device name: krillin
channel: ubuntu-
Two SIMs installed, SIM in the second slot is PIN-locked.
It's possible for a PIN to be entered on the SIM auto-prompt screen ( displayed at boot ) and the subsequent action ( ie. the DBus EnterPin call to ofono ) to get dropped. This results in the SIM still being locked when the user dismisses the greeter.
This bug was discovered while testing an ofono vivid silo. The associated ofono merge request is:

There's some kind of race condition involved, as this seldom happens ( ~5% of the time ).
I was finally able to prove that this was unity8 ( or some other upper layer component ) by adding info log messages to the ofono functions that handle the DBus EnterPin method, and the associated callback function. The scenario that clinched it for me was:
1. Boot phone
2. Enter bad PIN and tap check button when prompted for SIM2
[ See that remaining Retries is reported as 2 ]
3. Enter PIN again and tap check button again
4. Examine syslog and notice that there's only a single call to EnterPIN, which is followed by a log message showing callback failure for the bad PIN entered.
