Messege: Gnome-Message: gnome_execute_async_with_env_fds: returning -1

[Amir Bukhari <ufz6@rz.uni-karlsruhe.de>]

I have debian 3.0 woody with gtk 1.2 and I use eXceed for windows as X 
Server.
when I start gnome (gnome-session) i receive this error:
---
Gnome-Message: gnome_execute_async_with_env_fds: returning -1
Gnome-Message: gnome_execute_async_with_env_fds: returning -1
Gtk-WARNING **: gtk_signal_disconnect_by_data(): could not find handler 
containing data (0x81B6890)
---
what does it mean? and why it come?
is there a solution?
