Description of problem: Copy message(s) to dialog box doesn't work as
it should be, obeying keyboard commands, where once you're in the
dialog, hitting a key on the keyboard (say the "f" key), should scroll
to folders that begin with "f"


Version-Release number of selected component (if applicable):
evolution-1.4.5-7

How reproducible: Always


Steps to Reproduce:
1. Select a message, then right click it
2. Select Copy to Folder
3. At the pop-up, let's say you have a folder named "fedora" and
another named "gnome", try hitting the "g" key, and it will go nowhere. 
4. To move it to the "gnome" folder, you have to scroll thru the
entire list, before clicking on it with the mouse
  
Actual results:
Keyboard input does nothing

Expected results:
Keyboard input of said character should move to the next folder
available, starting with the input character. So assuming there's a
"gnome" and a "godzilla" folder, it should go to one first, then
scroll to the other, providing options - you don't have to use the
mouse for this!

Additional info:
Works on Evolution that's not included in Fedora, so this looks like
some Fedora non-compliance - GNOME's HIG does state keyboard access is
important
