Message boxes are managed by the underlying toolkit (Qt4 or GTK+), which 
finally decides how he will arrange the message box buttons.

If I remember well, you use gb.qt4 on a Gnome desktop. In that case, I think 
Qt4 detects Gnome and tries to follow the GTK+ message boxes layout, where 
some buttons (there are some "standard" one like "Yes", "No"...) are put from 
right to left.

I have often that problem when implementing gb.qt and gb.gtk: either I rewrite 
the feature myself, so that it behaves exactly the same in both toolkit, 
either I use the function provided by the toolkits, and you will lose some 
control on the situation then...
