i use tab complete all the time.
on 9.04 if you start typing the name of a directory then hit tab you get somthing like this

cd Doc<tab>
cd Documents/
this immidiatly lets you type the first few letters of the subdir you want and use tab again....

on 9.10 this has changed so you get the name of the dir
but with a space after and no slash

this means you end up typing, a few letters, a tab, a backspace a slash, some more letters, another tab, another backspace another slash, etc etc.

this is very annoying

how do i change it back to the old behaviour?
