It seems Dejunk is producing taint because of its Category variable in bindings.xml.

To reproduce:

1. Reload game client with all addons disabled, except Dejunk.
2. Open the Options Panel.
3. In the sidebar, click on Keybindings. (Important)
4. Exit the Options Panel.
5. You should get the taint dialog box now.
6. Do the same test without Dejunk loaded.

Please see this thread for more info. You find a working solution in post 9 of that thread.

So, in your case this would be:

category="Dejunk"

as plaintext string (not a variable). Or "Dejunk " if you are already using Dejunk as global.
