Summary0001114: crash when dragging a region with right mouse button
Description
This crash is maybe similar to bug 0001086, but it is 99% repeatable
although not fully predictable with a finite set of actions.

- Press the right mouse button inside a region
- drag outside the region
- release the mouse button.
- repeat this many times

=> Ardour crashes just when the mouse button is released
It sometimes happen after repeating 5 or 6 times, sometimes after 50
times.

Since there is no right mouse drag feature, it is probably related to
the context menu.
I could reproduce with two different builds, on two different machines
(a Sarge and a Sid).
It happens much more sooner in debug mode. I just had to drag 3 times.
Not sure, but I also noticed the crash is much easier to reproduce when dragging inside the same track (horizontally)

The crash happens in "range mode" as well. Not only in object mode.

i remember fixing this in ardour2, based on a complaint on IRC. it was caused by not checking whether the mouse release was still on a region.
