extract_tap_output() returning something means it just saw a TAP header. So this error realistically only happens when there's no TAP at all :P
My allusion to malformed KTAP is in the sense that KTA<random stuff>P ver<more stuff>sion 1 is malformed.
We could potentially be more completely precise w/ our error message and say "no K?TAP header found", but I initially thought this might be a bit more user-friendly.
