[lucid] Ubiquity suggests default hostname as "-laptop-laptop-laptop-laptop-laptop"

I've just tested 20100225 image and the problem still exists.
It's driven by typing username - after every letter written in username form the more "-laptop" strings are appended to hostname.

I just saw the same thing on Alpha 3.

Confirmed for Alpha 3.

This bug was fixed in the package ubiquity - 2.2.0

---------------
ubiquity (2.2.0) lucid; urgency=low

  * Removed the alpha warning. Welcome to Ubuntu 10.04 Beta 1.
  * Align labels to the top on the language page (LP: #532876).
  * The run method of GTK+ dialogs enters a nested main loop. However,
    the user can click the quit button (which calls the quit dialog's
    run method) before the page is ready. Once the page is actually ready,
    another main loop is entered, and thus if the user hits the quit button
    on the quit dialog at this point, nothing will happen. Work around this
    by managing the state of the quit dialog in the frontend.

  * GTK frontend:
    - Fix label retranslation when clicking on update link (LP: #531864).
  * KDE frontend:
    - Use manual xauth code and sudo rather than kdesudo; the latter does
      not permit passing through environment variables other than
      one-by-one, which broke various things (LP: #526456, #538142).
    - Construct the default hostname from the text in the username box, not
      from the previous text in the hostname box (LP: #527704).
  * Automatic update of included source packages: console-setup
    1.34ubuntu11, grub-installer 1.49ubuntu7, partman-base 138ubuntu3,
    partman-target 64ubuntu7.

  [ Jonathan Riddell ]
  * Ensure progressDialog is kept updated (LP: #538147)
  * Set Qt style accelarators on question dialogue
  * Do OEM config UI setup after translate_widgets, (LP: #539176)
