Comment 4 for bug 145218

I don't think we should fix this. IMHO, it's not a bug.

Rationale is:
- if a program from package X is installed in /usr/bin (or any system-wide path) and is supposed to be used as a launcher for a particular mime-type or file extension, yet firefox does not propose it, it's probably package X's fault to not have the proper mime referenced and then, the bug should be against X, not firefox.

- the "Other" choice points to user home dir as in traditional Unix, that's the only place where a user could install stuff without privileges and user may not know how to specify a correct user-defined mime type.
