I've been bitten by similar issues often enough that I regularly git
clean -dfx my checkouts or at least pass -r to tox so that it will
recreate its virtualenvs from scratch. Yes it does add some extra
time to the next test run, but you can iterate fairly tightly after
that as long as you're not actively moving stuff around while you
troubleshoot (and coupled with a git hook like Doug described for
cleaning on topic branch changes would be a huge boon as well).
