Crash when attaching photos

Ubuntu Phone 14.04(r3), Meizu MX4.
Attaching one or more Photos from the gallery reliably crashes gmail app.
On the MX4, the usual file size of photos is 2-4MB. Gmail app reproducibly crashes when adding files of this size (white screen of death).
Rather annoying. Users will want mail photos.

Another issue is that mailing files this size is ridiculous anyway. There must be provided a way of reducing file size prior to mailing the picture.
