This would complicate adding new files from the file system as the md5
database would need updating. I'd like to keep the system a simple as
possible. If someone is concerned about duplicates he could run one of
the many deduping tools available for Linux (and other OSes probably
too).

Images are not always linked to the detail page (?nolink option or
when wrapping the image in a link). This page should be accessible
from the media popup then.
Or maybe we should have a full screen (as opposed to the popup) media
manager with old revisions and a minimal popup for inserting and quick
uploading files? It might make sense to have a look at how other Wiki
and CMS engines handle that to have some inspiration...

I'd like a third option: "both". That should be default IMHO.

I don't think we need that.
There's one more thing we haven't talked about: diffs. As soon as we
have revisions, we also need a way to see differences. This should be
implemented in a way that is easily extendible by plugins. By default
I'd only implement something for images. Github just recently added
some pretty nifty features for image diffs:
https://github.com/blog/817-behold-image-view-modes - I think at least
the onion skin thingy should be easy to implement using the CSS
opacity method. We'd also need a way to compare the image metadata
(EXIF).
