Ah, it seems I didn't remember to actually present that information.
I.e., the presentation layer has always received the data, but didn't
bother to ever print it.

I just checked in a fix in the repository at
https://svn.process-one.net/contribs/trunk/eunit, that prints the output
(truncated if it gets too long) if there is any.

In general, EUnit bug reports can be filed at
https://support.process-one.net/browse/EUNIT.
