Start at var/search/selenium_search.py around parse_search_results and lib/core/settings.py around parse_blacklist, then reproduce the command `zeus.py -r -W -E` in the reported environment. Check how BLACKLIST_FILE_PATH and the log/blacklist directory are created and opened; done means the reported permission failure is handled or prevented without an unhandled exception.
