This bug was filed from the Socorro interface and is 
report bp-76e1c621-42ea-4da7-9576-98c130170531.
=============================================================

There are 7 crashes in nightly 55 with buildid 20170531100318. In analyzing the backtrace, the regression may have been introduced by patch [1] to fix bug 1367837.

It seems unlikely that this would be caused by bug 1367837. More likely one of Botond's scrollbar dragging patches.

From the backtrace it looks like maybe state->mController is nullptr in NotifyScrollbarDragRejected?
