Firefox hyphenation tools missing

Firefox doesn't seem to have its hyphenation tools available on my machine. I believe this is related to bug 894166, which is where the standard firefox hyphenation tools were replaced with a symbolic link to the system hyphenation tools. The symbolic link is there, but it's broken. From what I can tell, the /usr/share/hyphen directory is provided by the packages hyphen-en-us and openoffice.org-hyphenation. I think there should be a dependency (or at least a Recommends) added for one of those packages, or something else that provides the right tools.
