Building LAT 1.2.3 with gtk-sharp >= 2.12.0 results in a bunch of warnings about the use of deprecated/obsolete API's relating to the Name property of the "about" dialog and the tooltips. The attached patch fixes these for me but of course will bump the gtk-sharp version requirement accordingly, so you might want to wrap the effects of the patch in a conditional and test for gtk-sharp >= 2.12.0...
