        Hi,
the last time I debugged a similar error with Andre (on 3.26) it turned
out that evolution/IMAPx code asked for a message in a folder which
didn't contain that message anymore. The "Empty cache file" means that
the file can exist, but is zero-sized. It can mean that the local cache
content doesn't correspond to the server-side folder content. It can
happen easily when multiple clients are accessing the same account at
the same time (I can do it when I move message from one folder to
another while another application still sees the message as available
in the original folder (having set real Trash means the messages are
moved in the background); that was my reproducer at least, but such
situation might be rather rare).

As the claims are mostly about your Trash folder, could it be that
you've setup the server (in the Web UI) to empty Trash often? I'm
wondering whether Yahoo! servers can change the folder content somehow.
Though more likely is some issue in the IMAPx code in evolution-data-
server.

As a workaround, I'd try to disable real Trash for the account, which
you can find in Account Properties->Defaults tab. Just unset the
checkbox beside "Use real Trash folder", similarly with the Junk
folder.
        Bye,
        Milan
