I get this when using:

const tape = require('tape')
const {test} = tape
tape.createStream()
  .pipe(require('tap-spec')())
  .pipe(process.stdout);

And calling t.err(error) on an error that contains endlines in the message body.

I had this problem also. I noticed that tape-spec depends on tape-out, I ran it on tap-out and found it crached with that error message. It turns out that tape-out sometimes breaks on lines that don't begin with ok, not, or #. So it put in and extra filter to put a # on lines that begin with a space

(some-test-rig) | sed 's/^ /#/1' | npm tap-out

and then it passed the particular output I was throwing at it. But I think there are more issues besides just this one.
