Fonts in the attached file are very ugly and jaggy when the file is rendered by Poppler's Cairo backend. Note that this is not a scanned image file.
The bug can be reproduced with current HEAD using gtk-cairo-test, and also with Evince. On the other hand, the file is rendered correctly by gtk-splash-test, Okular and xpdf. I use Ubuntu 9.10.
Since the file is too large to be attached, I'm posting a link:

Scratch that, found a way to post only the first page.
It's a known issue, thanks for reporting.
