If you have an add-on that creates custom node types and then uninstall that add-on, assuming the add-on doesn't remove all nodes with that custom type you'll get this error:

Code:

Now, I realize I could just remove all nodes with that node_type_id but that seems like it could potentially be a bit too destructive if those nodes would contain content, so maybe it'd be a better to have the nodes be ignored if the add-on is uninstalled rather than attempting to load no entity :)

I've fixed this now, thanks. However, just to comment on something:

Now, I realize I could just remove all nodes with that node_type_id but that seems like it could potentially be a bit too destructive if those nodes would contain content
Add-on uninstallation is, by definition, destructive. All data created by the add-on is expected to be deleted on uninstallation.

If you're adding a node type, you're presuming adding additional tables to store the data for those nodes, so you'd be removing that anyway. There's not really any point in keeping around an unusable node record.
