Done in my repo too. 

I've also figured out what the problem with my test file[1] was, it
wasn't a bug in poppler, but in poppler clients. I've fixed the problem
in the poppler glib demo application (thanks to ickle and adrianj), and
the output looks much better now[2], although still a bit different from
acroread[3] and xpdf[4].
