Status: RESOLVED DUPLICATE of bug 1012466

(Toolkit :: Telemetry, defect)

Description

[Chris Peterson [:cpeterson]]

When I run Nightly from the OS X Terminal, I see the following JS exception logged to stderr when I quit the application. I can reproduce this error with  33 and Aurora 31, but not Beta 30 or Firefox 30:


1402528565855   addons.manager  ERROR   Exception calling provider shutdown: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIObserverService.removeObserver]"  nsresult: "0x80004005 (NS_ERROR_FAILURE)"

I also faced this exception when running mochitests against Mulet (an hybrid product between b2g desktop and Firefox).
Adding try/catch around two throwing remoteObserver fixed the crash at end of mochitest runs.

I don't know about the crashes when using Firefox as a regular user,
but these two fixes allowed me to run mochitests on Mulet without crashes during shutdown!

Please file a new bug for the Identity issue - it sounds like that module might also have a shutdown ordering issue and could possibly use the barrier exposed in bug 1012466.
