In case it helps, I found out this:

Using emacs-24 rev. 107994 (your original patch):

./emacs -Q -fn "DejaVu Sans Mono-10" -l bug.el
=> "Should be nil: nil"

./emacs -Q -fn "DejaVu Sans Mono-12" -l bug.el
=> "Should be nil: t"

In both cases, the latin letters use the given font, and the Hebrew
letters are displayed with corresponding "Arimo" font:

    xft:-unknown-DejaVu Sans 
Mono-normal-normal-normal-*-16-*-*-*-m-0-iso10646-1 (#x44)
    xft:-unknown-Arimo-normal-normal-normal-*-16-*-*-*-*-0-iso10646-1 (#x9BD)
