And I have just remembered the other way I worked out to get around my
problem.  I uninstalled the MythMusic package (on Mythbuntu).  That
allowed the upgrade to complete, and then when the MythMusic package
was installed again, the next time the frontend was started, it did
the MythMusic database upgrade but this time the message window was
visible.  If MythMusic is still in a separate package in 0.28, that
might work for you.  Even though you are not using MythMusic, if it is
installed it will have database it needs to upgrade.
