I was calling "g_value_get_string( &value )" and this function failed.
That's why I did see
an empty string.
I didn't look at the GTK+ sources but it looks like the value
retrieved is just an address
of the string and not the string itself.
I do have a workaround. I didn't test it yet, but I'd prefer to get
this info this way.
Is there anything else?
