Problem summary Nuke crashes when Read nodes display an error in the Viewer. The issue appears to only happen on Windows 10.
This can happen when a Read node's colorspace cannot be found in the current OCIO config, or when reading an MPEG4 or h264 file into Nuke Non-Commercial.
Customer reported version Nuke 13.0v5
Customer reported platform Windows 10
Steps to reproduce
1) Open Nuke.
2) Navigate to Edit > Project Settings and open the Color tab.
3) Ensure that color management is set to Nuke and OCIO config is set to nuke-default.
4) Create a Read node, and select any footage. At this point, the file should be read in as expected.
5) On the Read node, change the colorspace knob to any value, other than the default.
6) Now set color management to OCIO and the OCIO config knob to either aces_1.1 or aces_1.0.3.
Alternative reproduction steps
1) Open Nuke Non-Commercial.
2) Read in a MPEG4 or h264 file.
Expected behaviour Nuke should not crash, and should display an error for the Read node.
Actual behaviour Nuke crashes when Read nodes display an error in the Viewer.
Workaround Unknown.
