Item has already been added

See original GitHub issue

Getting the following error when attempting a pull or quick-export (and probably other actions, too… dunno!).

Item has already been added. Key in dictionary: ‘TMP’ Key being added: ‘tmp’

This just started happening on a system where things had been working fine previously.

Here’s the stack trace:
