gnome nor xfce come up

[Marcelo Laia <marcelolaia@gmail.com>]

I try to start gonome and got this error output:

/etc/gdm/Xsession: Beginning session setup...
SESSION_MANAGER=local/laia:@/tmp/.ICE-unix/17100,unix/laia:/tmp/.ICE-unix/17100
1242136429.423451 Session manager: disconnected...
/usr/bin/gnome-session: symbol lookup error:
/usr/lib/gio/modules/libgvfsdbus.so: undefined symbol:
g_vfs_icon_get_type

I try google ( http://tinyurl.com/qgt6ob ) but got only 2 pages on France (fr).

So, I install xfce4. I can log in it (gdm), amsn and skype goes up
automatically, but anything are able for to do. I dind't can start any
program.

I am using TWM now.

Any clue?

Thank you very much
