GTK partition bars do not repaint when their position changes

This appears to be due to using an GtkEventBox. Packing the SegmentBar in a GtkFrame fixes the bug.

This bug was fixed in the package ubiquity - 1.12.10

---------------
ubiquity (1.12.10) jaunty; urgency=low

  [ Evan Dandrea ]
  * Fix a crash when in OEM mode. Child widgets are members of the
    self.userinterface list (LP: #361668).
  * Add support for displaying the "Use the largest continuous free space"
    option in the partition bars. Previously ubiquity would create a single
    Ubuntu partition that filled the entire drive when this option was
    selected (LP: #289663).
  * Pack the SegmentedBar widgets in GtkFrames rather than GtkEventBoxes
    to work around repainting issues (LP: #362334).
  * Automatic update of included source packages: flash-kernel
    2.13ubuntu7, user-setup 1.23ubuntu20.

  [ Colin Watson ]
  * Fix stripping of '=dev=' from device names when creating partition bars
    to avoid reducing e.g. '=dev=vda' to 'a' (LP: #362466).
  * KDE frontend:
    - Start the resize slider at the maximum possible size for the partition
      being resized; this is in line with the GTK frontend, and fixes the
      situation where the previous default (half-way between the minimum
      size and the current size) is out of range.
    - Use a better colour to represent the results of automatic partitioning
      (LP: #348461).
  * Preseed tzsetup/selected up-front rather than filtering it and then
    preseeding it; filtering it causes the backup state to be reset, which
    causes an infinite loop when backing up from the timezone page when the
    default country only has one timezone (LP: #361674).
  * Preseed passwd/auto-login-backup=oem in OEM mode, so that the original
    configuration files are available for restoration (LP: #361272).
  * Add a little extra state machine debugging to the partman component.
  * If an error/question dialog is displayed while changing steps is
    disabled, we currently need to re-enable changing steps in order to get
    a normal cursor, but that also enables the Back/Forward buttons and
    allows people to violate assertions by being too quick (e.g. selecting
    an autopartitioning choice while the installer is still busy analysing
    the possible choices). We should clean this up properly later, but for
    now just restore the allowed-change-step state when the dialog is
    finished.
  * Fix preseeding of the autopartitioning question to work in automatic
    mode: it needs to be preseeded as unseen, otherwise going back from a
    confirmation question doesn't work (LP: #361828). Remove an old code
    path that would have been very complicated to fix for this and is
    guaranteed to never be used nowadays.
  * Update translations from Launchpad.

  [ Jonathan Riddell ]
  * KDE frontend:
    - port reboot code to KDE 4, (LP: #360838)

  [ Mario Limonciello ]
  * Mythbuntu Frontend:
    - Don't launch GUI applications from within the chroot as this causes
      problems when libGL.so.1 and friends are diverted. Instead bind
      mount the necessary files to launch them outside the chroot.
      (LP: #362419)
