Bug Description

Binary package hint: gdm

affected package (probably): gdm (2.30.0-0ubuntu5)
ubuntu release: 10.04 LTS (Lucid Lynx)
system language: german (switzerland)

bug description:
Using the character "&" in a username (the complete or extensive name which can be changed through the users administration GUI "users-admin") will result in very weird behavior in the GDM login screen: mostly the username itself is replaced by "(null)" or another username which doesn't contain the character "&". Another time no username (and panel) shows up at all and you can't log in through the GUI. In the users administration program "users-admin" the usernames on the left side containing a "&" are also replaced by another non-affected username. If you change the affected usernames into something else without a "&" everything works fine again.

The gdm-package 2.30.2.is.2.30.0-0ubuntu2 in PROPOSED suffers from a regression. The following upstream fix (see changelog) doesn't work anymore

* New upstream bug fix release:
    - When the face browser is disabled, the PAM conversation is started
      immediately, so users do not need to click a button to start entering
      the username and password. (GNOME #591082)

gdm 2.30.2-0ubuntu1 works fine.

2.30.2 was reverted from -proposed because it caused other
regressions. The regression you reported is only against a version in
-proposed which never made it to -updates, to the reversion is more
important right now.

I've managed to reproduce the bug with the gdm version available on Lucid and I can confirm that the package on the proposed repository indeed fixes the issue. Marking this as verification done. Thanks all.
