Sorry- I wasn't done yet -- hit the wrong key and it sent the mail out ;-(

Anyway, I got the database updated successfully and could get into the
frontend (yay!).

I even switched the theme back and forth between Terra and Mythbuntu.
No problems.

Then I restored the MythMusic plug-in.  Boo!  The dreaded freeze
returned. I thought maybe it was a problem with a pop-up window by
another user account (e.g. mythtv?) that couldn't open a window
because I (default account) had the xdisplay locked up, so I issued
the command "xhost +" and tried again, but no joy.  I tried sending
the frontend a HUP signal and it responded (in that it made entries in
the log that I was following in another xterm with tail -f
mythfrontend.log).

So the short of it is that when the MythMusic plug-in is installed (as
it is in my 10.04 system) the frontend sees the music schema is
outdated, creates a mysql database backup, reports the backup complete
and ....????  It stops doing anything useful at this point, but it is
not dead.  No display updates (still a blank screen), no pop-ups,
nothing.  I have to kill it to try again.  Anyway, for the gurus in
the crowd, I pasted the whole sorry mythfrontend.log file to pastebin.
 It should be visible from this url:
      http://paste.ubuntu.com/7201131/

I would really appreciate it if someone could get me moving forward
again.  I'm totally sick of this mudhole.

Thanks for helping out.
