I'm generally very happy with the Joomla-SMF bridge, but I've encountered one problem.

Most attachments on posts on the forum become corrupted during the download. The only ones where this appears not to happen are plain text files. I know it's a problem with the download, not the upload, because the files on the server are not corrupted, only after downloading they are. It appears to be a problem with the bridge since it only occurs when I patch SMF via the Joomla-SMF admin utilities, on the unpatched SMF, the attachment downloads work just fine.

I'm using Joomla 1.0.9 with SMF 1.1.3 and Joomla-SMF 2.0.2.

Curiously enough, when I installed a fresh Joomla! (even of the exact same version) and SMF and the bridge, it worked there, so maybe one of my files is damaged and causing this?

Any idea where I should start looking?
