<Swing Dev> [PATCH] fix GTKLookAndFeel crash on recent versions of GTK

[Kirill Kirichenko]

Hi Thomas.

I'm responsible for GTK L&F.

I's a bit straightforward way. At least we can add a GtkEntry there. We 
add Entry and Button in a ComboBoxEntry because we render JComboBox by 
parts in Java and in previous versions Entry and Button had to be in a 
ComboBoxEntry because they rendered differently if their parent was a 
ComboBoxEntry. Best way here is to find out how ArrowButtons are 
rendered in native gtk and do the same in our code.

Unfortunately I'm busy at another project for 100% of my time. Such are 
priorities.

It you find another solution I'd like to have a look.

Thanks for your comments.
Kirill
