=============================================================

java.lang.NullPointerException: Attempt to invoke virtual method 'void org.mozilla.gecko.db.LocalBrowserDB.removeThumbnails(android.content.ContentResolver)' on a null object reference
	at org.mozilla.gecko.db.BrowserDB.removeThumbnails(BrowserDB.java:229)
	at org.mozilla.gecko.MemoryMonitor$StorageReducer.run(MemoryMonitor.java:237)

This is the same as Bug 1077858. We're calling a static method on BrowserDB when it hasn't been initialized.

The interesting part about this bug is that Gecko is running (we check earlier in the method), so this implies some really unlikely timing -- that we managed to run StorageReducer before GeckoApp.initialize ran.

Again, that implies a window focus issue. But this happened on a 10-31 build, which should be after we turned the first-run experience into a dialogfragment.

This will either be fixed by Bug 1085591 (if the issue is focus-related) or Bug 1077590.
Depends on: 1085591, 1077590
This should now be impossible after Bug 1077590.
