Comment 1

[Ioana Chiorean]

I can see from the reports that it occurs mostly on Acer devices (only one other lenovo ):

Comment 2

[Aaron Train [:aaronmt]]

java.lang.NullPointerException
	at java.util.HashMap.get(HashMap.java:307)
	at org.mozilla.gecko.gfx.LayerView.runTouchInterceptors(LayerView.java:242)
	at org.mozilla.gecko.gfx.LayerView.onTouchEvent(LayerView.java:273)

Comment 3

[Kartikaya Gupta (email:[e-mail])]

This stack is bogus. Line 242 in LayerView.java in the 28.0 release is this:

for (TouchEventInterceptor i : mTouchInterceptors) {

where mTouchInterceptors is an ArrayList. There's no calls to HashMap.get in that line. The Acer devices must have a busted dalvik or something.
