Masked glare behind glass Reference Photo

Consider the following photograph:



No Glare

The first render resembles:



Note how the LEDs have no glare.

Glare

The second render adds glare by following Price's tutorial:



Problems

Adding glare introduces a number of problems (in no particular order):


Since the glare is added during compositing, the cabinet door glass does not affect it.
The star streaks are not pointed.
Separating the cabinet door frame and cabinet door handle for masking eliminates incorrect glare, but produces a moiré pattern for the handles (even with dithering and DoF in place).
Due to issues with alpha, the white environment background is no longer applied (this is not apparent with the glare reference image because JPEG does not support transparent backgrounds). This cascades to other problems (such as darker tiles and less window reflection).


Question

How would you produce a realistic glare (or glowing LEDs) that is behind glass and correctly masked?

Compositor Node Setup

Here is the node setup:



(Aside: does Blender have an "save node setup as image" option? A screenshot won't necessarily capture a massive node setup.)

Glass Nodes

The glass nodes have the following node setup, from chocofur's tutorial:



And the absorption:
Try adding a refraction  node to your door material, so that the light gets dispersed



Edit:
In you file the glare is there but it's almost wiped out by the white environment's brighness:
