Many GTK warnings

[houghi]

I am running Debian Wheezy 7.4. I run XFCE 4.10
When I run several programs, I get warning.

e.g.
houghi at penne : /usr/bin/gvim
(gvim:20300): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::sm-connect after class was initialised
(gvim:20300): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::show-crash-dialog after class was initialised
(gvim:20300): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::display after class was initialised
(gvim:20300): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::default-icon after class was initialised
(gvim:20300): GLib-GObject-WARNING **: Attempt to add property GtkSettings::gtk-menu-bar-popup-delay after class was initialised
(gvim:20300): GLib-GObject-WARNING **: Attempt to add property GtkSettings::gtk-label-select-on-focus after class was initialised
(gvim:20300): GLib-GObject-WARNING **: Attempt to add property GtkSettings::gtk-button-images after class was initialised
(gvim:20300): GLib-GObject-WARNING **: Attempt to add property GtkSettings::gtk-can-change-accels after class was initialised
(gvim:20300): GLib-GObject-WARNING **: Attempt to add property GtkSettings::gtk-menu-popup-delay after class was initialised
(gvim:20300): GLib-GObject-WARNING **: Attempt to add property GtkSettings::gtk-menu-popdown-delay after class was initialised

I have a workaround by using an alias for this (and some other programs)
where I have:
alias gvim='gvim  2> /dev/null'

This is a workaround, so I do not see the warnings all the time. I DO want
to get really rid of them.
When I searched, all I got was that these are only warnings and that I
should solve the issue. Not really helpfull if you have no idea what the
issue is.
Some also say it is the application that I am running, which I doubt as I
did not compile them myself and use the debian repos. As there are so many
programs, I doubt this is due to the programs them selves, but rather one
or several of the libraries.

My guess is there might be 3 reasons:
1) By adding testing as a repo to get XFCE4.10 running, the rest is not up
to date anymore and this causes problems.
- If this is the case, what can I update to testing, without going to
  testing completely?
2) Not everything is installed that I need.
- If this is the case, what do I need to install
3) Everything is installed, but not everything is running
- I have in 'Session and Startup' at Advanced "Launch GNOME services on
  startup" activated. Deactivating does not change anything. Is there
  anything else I must do?

Obviously this is pretty annoying as this works with almost any program,
e.g. xfce4-about, yad, ...

I have put the output of `strace -oxfce4-about.txt xfce4-about` at
http://houghi.org/Fun/xfce4-about.txt so you can perhaps help identify the
problem and help find the solution.
