https://tbpl.mozilla.org/php/getParsedLog.php?id=21196650&tree=Mozilla-Inbound mdas/jgriffin, can one of you please look at this? We hit it across a variety of B2G test suites.
I'm planning on trying to track this down today.
FTR, this is 100% a Gaia bug. The question is, can we get someone on the Gaia team to fix it, or do we have to implement a workaround.
Depends on: 856082
Pushed a new emulator to try to make sure it doesn't break anything. If it doesn't, I'll land on inbound to see if it makes this intermittent failure disappear. https://tbpl.mozilla.org/?tree=Try&rev=61d9ffc98086

@scravag, can you assign someone to look at this? This error reported by Gaia is causing intermittent failures in all B2G tests in TBPL. It looks like a problem opening the window_manager indexedDB at https://github.com/mozilla-b2g/gaia/blob/master/apps/system/js/window_manager.js#L567 The error is: UnknownError at: app://system.gaiamobile.org/js/window_manager.js line: 567

Ben, do you have any idea why Gaia would intermittently be throwing this error while attempting to access the window manager's indexedDB on startup? It's causing a degree of random orangeness in TBPL right now.
Flags: needinfo?(bent.mozilla)
Not offhand, no. "UnknownError" is our catch-all error for "something that should never happen". We'd need a debug (gecko) build to tell us what's actually happening...
Flags: needinfo?(bent.mozilla)
We haven't seen this in a month, so I'm thinking this has been fixed.
