I'm finding the Blender crashes when opening an old VSE only .blend file (default cube, light and camera in 3D view) that was saved when I didn't have Filmic installed. This isn't a problem with geometry files, only ones with strips and modifiers in the VSE. This now means that all my old VSE project files cannot be opened.
An excerpt from the console when in debug mode:
Version 268 sub 0 date unknown hash . . . Color management: display "sRGB" used by scene not found, setting to default ("sRGB / BT.709"). Color management: scene view "Default" not found, setting default "sRGB EOTF". Color management: sequencer colorspace "sRGB" not found, will use default instead. . . . wm_window_make_drawable: set drawable 1 Error: EXCEPTION_ACCESS_VIOLATION
A quick test seems to show that the reverse might also be true, that new VSE only files cannot be opened in a copy of Blender without Filmic installed.
I have updated the start file to use Filmic valid defaults on load and the three warning messages disappear but the Access Violation still happens.
