I guess this is caused by running code with some resource released for shutdown.  I will try to listen on will shutdown to clean up the work queue.

Comment 2

[Honza Bambas (:mayhemer)]

Preventing nsCacheService::GetOfflineDevice() to return the device when nsCacheDevice::mInitialized is false will fix this bug.

Comment 3

[Thinker Li [:sinker]]

Since Bug 739868 will remove evicting code, I guess this bug would be resolved by it.
