Last update fixed the bug
iPhone 5, OS version: 8.1.2
Now the app doesnt crash at all, but it doesnt react to the "Open in.." button when pressed from a different app and Gmail is selected. For ex, I was trying to open a PDF in Gmail -- previously it would creat a draft with that PDF attached.
Annoying bug, but certainly can live with it.
