Needles must be a list error

Created by: amelio-vazquez-reina

I installed autojump from master, and I am working with the latest version of Zsh (5.0.5). I added:

[[ -s /path/to/autojump/etc/profile.d/autojump.zsh ]] && source /path/to/autojump/etc/profile.d/autojump.zsh

to my .zshrc, and everything works fine except for when I do:

j something_4 to select from one of the options available (there are 10 entries with the word something in it). When I do so, I get:

Traceback (most recent call last):
  File "/path/to/autojump", line 411, in <module>
    sys.exit(main(parse_arguments()))
  File "/path/to/autojump", line 400, in main
    find_matches(entries, tab_needle)))
  File "/path/to/autojump", line 165, in find_matches
    assert isinstance(needles, list), "Needles must be a list."
AssertionError: Needles must be a list.
autojump: directory 'something__4' not found
Try `autojump --help` for more information.

Why?
