Please remove your theme cache and see if this cleans up. If it does, a new theme upload is necessary.

I have verified this with 5 people now, that the cached theme suddenly seeing all this new stuff is causing the breakage.
I've uploaded a new theme to hardy to fix it. Folks upgrading will get an extra symlinked theme in /usr/share/mythtv/themes/Mythbuntu pointing to their old theme, but folks installing new will see two themes:

/usr/share/mythtv/themes/Mythbuntu-7.10
/usr/share/mythtv/themes/Mythbuntu-8.04

This will fix the breakage.

Ubiquity bzr revno# 2652 (ubiquity release 1.8.5) fixes this as well by defaulting to the new Mythbuntu-8.04 theme upon installation.

ubiquity (1.8.5) hardy; urgency=low

  [ Evan Dandrea ]
  * Move the map when the cursor is near an edge instead of whenever the
    cursor moves (LP: #214989, #195159).
  * Various fixes to the new tzmap. Thanks Colin Watson.
    - Wait half a second before zooming in.
    - Zoom in from the position of the mouse, rather than the top left
      corner.
    - Widen the hover-to-move areas.
    - Find the closest hotspot if there are several nearby.
    - Zoom to 4.5x.
  * Removed 12system_partitions_formatted. It now lives in partman-target.
  * Automatic update of included source packages: console-setup
    1.21ubuntu7, partman-target 54ubuntu6.

  [ Mario Limonciello ]
  * Default the MythTV theme to the newly changed Mythbuntu-8.04 theme
    to prevent upgrade crashes. (LP: #215036)

  [ Colin Watson ]
  * Allow diagonal scrolling in timezone map.
  * Update translations from Launchpad.
  * Fix typo in German welcome message (LP: #195075). This needs to be fixed
    in Launchpad or it *will* regress, but this will at least paper over it
    for 8.04.
  * Set OVERRIDE_ALLOW_PRESEEDING=1 while calling console-setup to force it
    to allow preseeding (LP: #188492).
