Ted's package is not confirmed to fix the crash, but worth testing anyway. At worst we reopen this bug. Ack for SRU.

This bug was fixed in the package fast-user-switch-applet - 2.24.0-0ubuntu7

---------------
fast-user-switch-applet (2.24.0-0ubuntu7) jaunty; urgency=low

  * Added debian/patches/73_max_users_from_passwd.patch which makes it so
    there is a maximum of 15 users that can be read from the password file
    before going into overload mode. In that mode there are no users shown
    from the password files, only logged in users and an other that will
    take you back to GDM. Fixes LP: #203217
  * Added debian/patches/94_user_manager_signals.patch which adds removal
    of signals on shutdown. Each of these signals are invalid if they're
    called anywhere after this function.
  * Updated 90_status_management.patch to better handle removal of signals
    which should fix LP: #285797
  * Updated 84_session_management.patch to properly disconnect the signals
    related to the DBus events it is watching.
  * 90_status_management.patch: Changing 'Online' to 'Available' fixing
    LP: #279057
  * 90_status_management.patch: More work into handling the pixels around
    the applet. This will be the final version for how those pixels are
    handled, closing LP: #272824

This update has been in intrepid-proposed for over three months, without any testing feedback. Can anyone please test this version and tell us whether it still works normally, and this bug is fixed for you? Thanks!

I don't see any difference in behaviour. Although I have to say, I don't see a crash anyway. Just the fus applet behaving strangely both in 2.24.0-0ubuntu6 and 2.24.0-0ubuntu6.1 versions (it becomes a kind of combined "pidgin-status/switcher" applet. I don't think that is intended behaviour.). Marking as "verification failed".

Since this package doesn't introduce a regression, and doesn't crash any more, it isn't verification-failed. If it doesn't crash for you in intensive testing, this is almost "verification-done".

Current SRU was removed from proposed for bug 279057. If this is still an issue, it needs to be reuploaded without string changes.
