kats, does this crash look like fallout from bug 781220?
status-firefox17: --- → affected
Maybe? A crash with that stack would only happen if we tried to screenshot before calling createLayerClient on the LayerView, and that happens during GeckoApp initialization, before we should ever be screenshotting. I suppose this might happen in some weird race conditions if the "don't keep activities" option is on (or Android otherwise decides to blow away GeckoApp from under us) but it's pretty darn narrow window of opportunity for this to happen.

The "more crash reports" link in comment 0 still has recent crashes, although the stack is different. Leaving this bug open for the new crashes, since crash-stats associates them with this bug.

Don't see this any more.
