        <pre>Multiple wayland clients (e.g. Weston check tests and client apps like
calibrator) are crashing with the following error:

libwayland: error: received delete_id for unknown id

Also seeing other errors emitted when running the Weston subsurfaces client,
like:

not a valid new object id (16), message sync(n)
not a valid new object id (44), message frame(n)

I've also seen the desktop-shell process die several times when running/closing
clients... I suspect this behavior is related too.

I will see if I can pull together some backtraces, as well.

First bad commit is either:
