All images (fullsize too) have extra NEWLINE character

I just installed G2RC2 on an OpenBSD system -- seems to install and run just fine. When I upload images (via several means), their thumbnails AND the originals show up broken. If I look at the JPG on disk, it's fine. When I download it via my browser (or lynx) and do a hex dump, it appear to have one extra character at the begining: a newline (character 10 dec)! Where does that come from?!

Here's the output from 'lynx -source -mime_header http://...' of a full-sized image via G2:

<BINARY DATA STARTS HERE, after TWO newlines>

I didn't have trouble with G1 1.4. There are lots of other PHP apps running successfully on this machine.
