At that time emacs-w3m is about to access the url "about:", and runs (file-exist-p "about:") at first in order to check whether "about:" is a local file. But IIUC, it should not trigger TRAMP; only a thing like "/about:" will trigger TRAMP. I can reproduce the same error with (file-exist-p "/about:") and a similar error with (w3m "/about:"), though such ones should not happen. Funny.
