[Gtk-sharp-list] unknown widget class 'GtkFileChooserWidget'

[Marc Glenn]

Hello guys,

We tried using save dialog box in Glade-3.4 and compile it under Mono( 
gtk-sharp ). This dialog box contains GtkFileChooserWidget widget.

Compilation was successful but upon running the application and as the
save dialog box showed,the filechooser widget was not present and an
error in the console was displayed.

This was the error:
(DebugTool:3980): libglade-WARNING **: unknown widget class
'GtkFileChooserWidget'


We are using
Glade-3.4
gtk-sharp-2.10
mono-1.2.5.1

Anyone experienced this problem before?

THanks in advance
