I have put together a minimal script to show the issue without requiring the installation of the BlendLuxCore addon:

You should include a description what the actual bug is.
I thought the problem was that keyframes can't be set on properties of custom nodes, or don't show up in the UI.

Simon Wendsche (BYOB) added a comment to T71362: Memory leak if both a shader and an AddonPreferences class are used.

it is not recommended to create and maintain a reference to an object type shader in the top level of a module (shaders are slow to create and use a lot of GPU resources)

Simon Wendsche (BYOB) added a comment to T66521: No datablocks flagged as updated on node property edit.

I have added update callbacks to all our node/socket properties, however you should consider that this means that every affected addon needs to implement an ugly workaround. In my humble opinion it would make more sense to implement the ugly workaround in Blender once and save all the addon developers the work and the mess in their code (plus the time they spend debugging until they even find the issue and this bug report).

Could you try a new master build from buildbot?
I havent checked code, but could confirm this issue in 2.79b. However in current master this seems to be resolved already?

I can confirm this, it is fixed in latest master.
I apologize for not checking earlier.

It is crippling any external renderer addon that uses Datablock ID Properties.

This sounds like a good idea to me.
I hope that external renderers will also be able to use this new editor, to display statistics as well as warning/error messages that happened during the export process (e.g. missing imagemaps).

Another thing that might be a bug: the field for the active camera in the scene tab is always highlighted in red and there are no cameras in the dropdown selection box, although there is a valid camera in the scene.
Official Blender builds do not show this behaviour.

I just tried to start Blender with --factory-startup option and it still crashes, so I doubt that it's caused by my startup scene.
Now I rebuilt Blender with make debug and started it with --factory-startup -d --debug-all and it runs without the startup crash (also with my custom scene).
So the crash is only happening with a default build made with a simple make without options. Is that a release build?
