ubiquity crashed with TypeError: cell_data_func() takes exactly 4 arguments (5 given)

[Paul Hoell]

This happened after the installer set up the disks and (probably) asked me if i wanted to import user profiles, i couldn't really see anything, because there was lots of text missing in the window.
The install itself went on even though the crash report kept popping up.

This crash has the same stack trace characteristics as bug #194688. However, the latter was already fixed in an earlier package version than the one in this report. This might be a regression or because the problem is in a dependent package.

  * /apps/metacity/general/num_workspaces should be an int, not a boolean.
  * Automatic update of included source packages: flash-kernel 2.28ubuntu29.

  [ Evan Dandrea ]
  * Don't try to connect signals on the release notes label in the oem-
    config version of the language page, as it doesn't exist there.
  * Construct a GtkTreeCellDataFunc with the correct number of arguments
    in the migration assistant plugin (LP: #829987).
  * Don't let the text wrap for the language names in oem-config.

  [ Stéphane Graber ]
  * Properly sort the keyboard list (LP: #770320)
