The change I found was definitely 3.13.0, so it's definitely possible
that you're hitting a different issue. Could you please file a bug
with whatever information you have? Specifically, any details of
permissions, extended attributes, filesystems, etc. would be good.

Meld doesn't actually build/link against anything; we import whatever
pygobject bindings we get from your default Python path, and whatever
they have been linked against is the GTK+ version you'll get. I'm not
sure what you're trying to do here though.

There isn't. I experimented a while ago with doing checksums instead
of reading the whole contents, and it made very little performance
impact.

So it sounds like you're suggesting sampling parts of a file to get
checksums? That sounds interesting, but honestly I think it's beyond
the scope of what Meld is designed to do.
