Comment 55 for bug 749986

@Renzo: The resize grip had to be disabled in Shotwell since it conflicted with widgets in the bottom corner. If you remove the patch from gtk you have to rebuild Shotwell without the 04_no_resize_grip.patch (you can find it in my ppa). If you fail to do so Shotwell will fail start with "symbol lookup error: shotwell: undefined symbol: gtk_window_set_has_resize_grip"
I am not aware of any other program that has to be rebuilt after dropping the resize grip from gtk but there may be others.
