Forming reference to reference

[Surya Kiran Gullapalli <skg fluent co in>]

Hi,
I've recently updated gnome 2.10 to 2.12, and my small application, 
which was using old gtkmm, now not working.

Thanks to sigc in this respect.

I've this function call for CellRendererText,
==================
signal_edited ().connect (sigc::bind<Gtk::Widget&>
           (sigc::mem_fun (*this, &CXCellRendererText::editing_over), 
widget)) ;
===================
where widget is Gtk::Widget&.

The compile error i'm getting is


sigc++-2.0/sigc++/adaptors/bound_argument.h:57: error: forming reference 
to reference type `Gtk::Widget&'
sigc++-2.0/sigc++/adaptors/bound_argument.h:64: error: forming reference 
to reference type `Gtk::Widget&'
sigc++-2.0/sigc++/adaptors/bound_argument.h:70: error: forming reference 
to reference type `Gtk::Widget&'


Any body have this kind of problem??

I looked at libsigc list, where a similar question has been put (in the 
month of june), but no answer to that..

Any help would be greatly appreciated.

Thanks in advance.
Surya
