I finally found a way to get a working combination using the existing
mir.mvp-demo snap available in the store. When I build a mir client
*.snap (still using deb2snap for now) it includes all of the mir
client libraries needed at runtime. However, the
/apps/mir/*/bin/mir-run script results in the mir client running
against the client lib included in the mir server application
(/apps/mir/*/debs/usr/lib/*/mir/client-platform).

This appears to not be compatible with snaps created against the
latest versions of 15.04 packages. If I make the following change to
/apps/mir/*/bin/mir-run I can successfully run the Qt example
application.

- export MIR_CLIENT_PLATFORM_PATH="$(ls -d
/apps/mir/snap1.1/debs/usr/lib/*/mir/client-platform)"
+ export MIR_CLIENT_PLATFORM_PATH="$(ls -d
$SNAP_APP_PATH/debs/usr/lib/*/mir/client-platform)"

If I create a custom mir server snap (including the change above)
instead of using the older mir-mvp-demo snap, I still get the original
error I ran into so it's looking like there might be an issue in the
latest mir client and/or server.

Here's the original error for reference:
