win32 Gnu Emacs: browse-url launches Firefox with 2 tabs with same link

[Sivaram Neelakantan]

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

On Emacs 22.2, Win XP, with the following settings

(setq browse-url-firefox-program "C:/Program Files/Mozilla Firefox/firefox.exe")
(setq browse-url-browser-function 'browse-url-firefox)

clicking on a link, or M-x browse-url-at-point launches F'fox with 2
tabs having the same link.

The *Messages* buffer just show

browse-url-firefox
Loading browse-url...done
Starting Firefox...

that's it.  How do I fix this?  And I just checked Emacs-22.1, I get
the same behaviour there too.  Doesn't matter if firefox was already
open or not, too.  And if I start Emacs with no-init-file, and load
browse-url, it works fine with IE (IE is the default browser).

In GNU Emacs 22.2.1 (i386-mingw-nt5.1.2600)
 of 2008-03-26 on RELEASE
Windowing system distributor `Microsoft Corp.', version 5.1.2600
