slow gnome session start

[Matthieu Imbert <matthieu.imbert@ens-lyon.fr>]

Hi.

Recently, after updating several gnome debian packages, the session 
startup time went from around 1s to around 10s (i have an ssd disk). How 
can i debug the cause of this?

Here is an excerpt of the list of packages which were updated:

[UPGRADE] gnash-common 0.8.10~git20110618-3 -> 0.8.10~git20111001-1
[UPGRADE] gnome-backgrounds 3.0.2-2 -> 3.2.0-1
[UPGRADE] gnome-dictionary 2.30.0-2 -> 3.0.1-5
[UPGRADE] gnome-icon-theme 3.0.0-4 -> 3.2.0-1
[UPGRADE] gnome-icon-theme-extras 3.0.0-2 -> 3.0.0-3
[UPGRADE] gnome-screenshot 2.30.0-2 -> 3.0.1-5
[UPGRADE] gnome-search-tool 2.30.0-2 -> 3.0.1-5
[UPGRADE] gnome-session 2.30.2-3+sid1 -> 2.30.2-3+sid2
[UPGRADE] gnome-session-bin 2.30.2-3+sid1 -> 2.30.2-3+sid2
[UPGRADE] gnome-session-common 2.30.2-3+sid1 -> 2.30.2-3+sid2
[UPGRADE] gnome-system-log 2.30.0-2 -> 3.0.1-5
[UPGRADE] gnome-system-monitor 3.0.1-1 -> 3.2.0-1
[UPGRADE] gnome-utils-common 2.30.0-2 -> 3.0.1-5

I can provide the full list of upgraded packages if needed.

Thanks in advance

best regards,
