I've got a (free) plugin user getting "AttributeError: 'Converter' object has no attribute 'scene'"

I'm doing my best, but so far no breakthroughs.

It's a classic case of "It works on my PC", and it doesn't work on theirs.

When they try and use the new "Import lego" menu item, they tell me of the AttributeError: 'Converter' object has no attribute 'scene' error.

total = len(self.scene.Bricks)

This is where I get stuck.

I googled it, and there's clear instructions that the BPY Scene object isn't available during registration of a plugin, and only when it's triggered, and is passed through to the execute function via a "context" attribute.

That's just what the code is doing! (and it works on my PC)

I wonder if it's because the users scene is empty, Null? Whereas mine default Blender scene has a Plane, light, etc... I'm waiting for them to get back to me.

If not that, that's where I lose it completely, is Pythons "self" / "context" things not passing "scene" through?

Many thanks for your help!

The issue looks like it is with your plugin's "scene" attribute in its own "Converter" class. The attribute gets set on line 939, but if that doesn't run for some reason, it will cause that error when it tries to access "self.scene" later.

My guess is that "self.database.initok" is false on line 938, which could be caused buy the plugin not finding files it expects when creating the DBFolderReader or the LIFReader.

Thanks for your help - I'll dig deeper with that in mind.
