Problem summary
DeepToImage crashes when DeepRecolor nodes are upstream.

Customer reported version
nuke.12.2v4

Customer reported platform

Steps to reproduce

1) From Nuke, create 2 DeepRead nodes and add footage.

2) Create a DeepRecolor node for each DeepRead node.

3) Add the DeepRecolor footage to each recolor node.

4) Create a DeepMerge node, then a DeepToImage downstream.

5) Open the Properties bin of the DeepToImage node and disable the volumetric composition knob. 

6) Select the DeepToImage node and press 1 on the keyboard to view it, observing performance.

Expected behavior
The image should be loaded in the Viewer.

Actual behavior
Nuke crashes when viewing the DeepToImage node downstream from a DeepMerge with 2 DeepRecolor nodes.

Workaround
Enabling the volumetric composition knob does not have a crash.
