This file is somewhat corrupted: mask parent's ID type is supposed to always be ID_MC (ID type of MovieClip), but in this file the type is simply 0 (which is not a valid ID type even).

How did you create such a file and can you reproduce the issue again?

This file is created from scratch in 2.78a.

  • Open Blender
  • Go to Compositing layout
  • Change Image Editor panel to Mask
  • Create a new Mask
  • Create a Square
  • Click on a vertex
  • Open Properties
  • Click on Active Point - Parent.
  • Crash.

I just followed these steps again and it crashed again.

Can confirm the issue, 'Add Square' and then select a mask point, and the id_type of points' parents remains to 0.

Fix incoming (will also do some doversion, so broken files will be working again too).
