987391 - weird lockscreen situation where it shouldn't show up, but does and won't unlock

Status: RESOLVED DUPLICATE of bug 980549

(Firefox OS Graveyard :: Gaia::System::Lockscreen, defect)

Description

[Dietrich Ayala (:dietrich)]

Nexus 4, seeing this regularly.

While this doesn't seem like a normal scenario at first glance, I'm concerned it might be a problem during updates, so reporting to get some eyes on it.

STR:

1. flash a build
2. disable lockscreen
3. back up all user data*
4. flash a newer build
5. stop b2g, restore the user data, start b2g

The lockscreen should be disabled at this point. However, not only does it show up, sliding to unlock doesn't work. Have to reboot, and then lockscreen is disabled.


* I'm backing up and restoring all the files/dirs listed here: https://github.com/autonome/fxos-scripts/blob/master/backup#L17

I have seen this a few times now and it's super bad. I've seen this in the logs, and it may be related:

E/GeckoConsole( 4778): [JavaScript Error: "TransactionInactiveError: A request was placed against a transaction which is currently not active, or which is finished." {file: "jar:file:///system/b2g/omni.ja!/components/SettingsManager.js" line: 70}]
E/GeckoConsole( 4778): [JavaScript Error: "NS_ERROR_UNEXPECTED: " {file: "app://system.gaiamobile.org/js/lockscreen.js" line: 971}]

I don't know what the "TransactionInactiveError" means, but maybe it means that something failed to manipulate the mozSettings. This seems similar to the Bug 980549, although the log is different.

Fabrice, Gregor - any ideas what can cause us to see the error in comment 2?

Duping against bug 980549 to consolidate efforts in one bug.
