This seems to happen at least with versions 3.20100815.6 and 3.20110225. Id didn't happen in version from about a year ago. I created a testing ikiwiki installation demonstrating this bug. The same comment can be seen at <http://rtime.felk.cvut.cz/~sojka/blog/posts/directory/post/> and at <http://rtime.felk.cvut.cz/~sojka/blog/posts/directory/>. The corresponding git repo can be cloned by
git clone git://rtime.felk.cvut.cz/~sojka/blog.git

+> Unfortunatly, that git repo seems to be empty.
+> Perhaps you forgot to push to it? Thank you for working
+> to provide a way to reproduce this!
