I solved the problem when answering to Laszlo and Albert (thnaks to both of
you). I realied that the error message (from the second problem) was related
to a directory that is not an Ubuntu nor one of mine  (>  Warning: /build/buildd/glib2.0-2.16.4/gobject/gsignal.c:2271: signal name
 `selection_changed' is invalid for instance `0x88e2998')

So I remembered that a week ago I wanted to test gtkparasite. I had to
enable assistive tecnologies. At the end I got an enviromental variable

It was sufficient to unset it and everithing is working correctly.

I hope this can help others that may  get into troubles like this...
