edit:
seems to happen when I scroll down on a recyclerview that is smaller than the screen (aka, no scrolling necessary)

I grabbed the source code and I did this in ObservableRecyclerView.java:227:

  for (View v = this; v != null && v != parent; ) {
      ViewParent temp = v.getParent();
      if (temp instanceof View) {
          v = (View) temp;
          offsetX += v.getLeft() - v.getScrollX();
          offsetY += v.getTop() - v.getScrollY();
      }
      else
      {break;}
  }

and it seemed to fix it.

I stumbled across this post when searching on the same bug. Turns out it has been around for a while, and is logged with google here:

• Issue 197291: AppCompatDialog crashes on selecting text

In case that helps you guys, or any future readers.
