Bug Description
The documented (and simple) approach for doing drag & drop in QML applications is currently crashing inside Ubuntu Touch.
Discussing the issue in the ubuntu-touch mailing list, people confirmed the problem, and pointed out that they have either worked around the issue by reimplementing drag & drop by hand (with onPressAndHold, etc) or are still waiting for the problem resolution.
This is an example that crashes, for instance:

After some further debugging, this seems to be the offending line:
Drag.active: dragArea.
Without it, the crash goes away and dragging works in Ubuntu Touch too.
