Reproduce the crash in the extension by opening home.html#/whatever in Chrome, then compare it with the working routes home.html#/?tab=perps and home.html#/perps/market/BTC. Inspect the route handling for invalid hash paths and use the expected behavior as the completion check: retrying an invalid URL should not show an error screen or crash.
