If it can be useful, I tried again after having installed

(ekiga:1855): Gdk-CRITICAL **: gdk_x11_atom_to_xatom_for_display: assertion `atom != GDK_NONE' failed
The program 'ekiga' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
(Details: serial 34 error_code 8 request_code 139 minor_code 3)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
