GTK3 breaks some elements of Snes9x-gtk interface, especially sound_input_rate cursor

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Launch Snes9x-gtk with GTK3 installed
2. Try to set up the sound_input_rate with the bar in the "Sound Menu"
3. It doesn't work

What is the expected output? What do you see instead?

You should be able to set up correctly the sound_input_rate with with this bar. 
Instead, it's always blocked to 0. Moreover, even if you are changing another 
option (such as joypad buttons) the sound_input_rate variable re-initializes to 
0 because of this misfunctioning element.

What version of the product are you using? On what operating system?

GTK3, on Arch Linux last version (26/06/2011).

Please provide any additional information below.

It used to work correctly with GTK2. I think that it is just a regression.

this problem affects the gtk2 version of snes9x-gtk when using gtk2-2.24.5, 
downgrading to gtk2-2.24.4 resolves the issue.  the gtk3 version of snes9x-gtk 
is also affected.

Crosspost: It's a bug in Gtk+ 2.24 and greater that causes it to not parse the 
older GtkBuilder file correctly. This is fixed in git at 
https://github.com/snes9xgit/snes9x. You can also run glade on the snes9x.ui 
file, save it, and recompile, and it will be fixed.
