User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9b5pre) Gecko/2008030504 Minefield/3.0b5pre

GTK+ (and also Qt, so it's an excepted standard on Linux) scroll items in a XUL:menulist (aka combo box) when the user just hovers them with the mouse and uses the scroll wheel.

Reproducible: Always

Steps to Reproduce:
1. Open Preferences window
2. Move your mouse over the menulist which controls the "When Minefield starts:"
3. Scroll with your mouse wheel
Actual Results:  
Nothing happens

Expected Results:  
It should select the next or previous entry.

Since firefox uses a native file open dialog, you can test expected behavior there. Open File->Open, and try to scroll over the "All files" combo box.
