I'm unable to reproduce this problem with the current Emacs trunk.  I get:

(top nil (something nil) (comment nil " a comment ") (comment nil " another comment "))

And this seems to work, too.

This looks like it was fixed by Ulf Jasper a while ago, according to the
git log, so I'm closing this bug report.  If you're still seeing this,
please reopen.
