I had this problem when I went back to the first step of the installer, and right when I clicked update this installer it triggered the error.

There was one time when I started installing, and as soon as I got to the point where I could click "Install", Ubiquity crashed with this same bug. I assume it's an issue that certainly needs to be fixed in time for Lucid's final release, considering it is potentially fatal.

This bug was fixed in the package ubiquity - 2.2.17

ubiquity (2.2.17) lucid; urgency=low

  [ Mario Limonciello ]
  * Remove unused install_bottom_eb from GTK frontend's install_window.

  [ Evan Dandrea ]
  * Catch invalid iterators in on_region_combo_changed (LP: #521851).
  * Don't let not being able to talk to the system bus crash the entire
    language page.
  * Translate the yes and no buttons on the quit dialog in the KDE
    frontend (LP: #561876).
  * Update translations from Launchpad.
  * Automatic update of included source packages: base-installer
    1.103ubuntu7, choose-mirror 2.29ubuntu3, partman-base 139ubuntu4,
    partman-basicfilesystems 63ubuntu4, tzsetup 1:0.26ubuntu8.

  [ Colin Watson ]
  * Skip copy_wallpaper_cache when running as oem-config.
  * Update finish-install.d/07oem-config-user for new location of KDE's
    oem-config-prepare .desktop file (LP: #557309).
  * Restore translations for oem-config-check and oem-config-udeb, lost in
    oem-config merge.
  * Display simple progress feedback using debconf-apt-progress while
    removing oem-config (LP: #558593).
  * Write locale-gen output from ubiquity-dm to /var/log/installer/dm rather
    than to the console.
  * Increase kernel flush times (dirty_writeback_centisecs to 3000, and
    dirty_expire_centisecs to 6000) during bulk data copying. Surbhi
    Palande suggests that this should make it easier for the kernel to pack
    blocks contiguously, speeding up ureadahead after installation.

  [ Amichai Rothman ]
  * Fix hang unless mouse is moved (LP: #556376)
