Bash completion has duplicate entries

Created by: aprokop

Not sure if I am missing something, but here is my problem:

$ grep free ~/.local/share/autojump/autojump.txt
31.6227766016   /home/aprokop/local/opt/freemind-1.0.1

so there should only be a single completion for free. However,

$ j free<tab><tab>
free__1__/home/aprokop/local/opt/freemind-1.0.1  free__2__/home/aprokop/local/opt/freemind-1.0.1

The completion entries are identical, and there should be unique completion for it. I'm using the current HEAD (8b525c1b).
