More than that -- the reason for the temporary file is dropping part
of a "file://" url (the fragment, IIRC), which apparently happens at a
low enough level that several different things that I tried all failed
in the same way.  So my guess is that the above would still not

And to clarify the reason for the temporary file: since the part of
the URL is dropped, the hack is to construct a temporary "trampoline"
file that has a redirection to the real URL, and that looks like the
only robust solution that actually worked fine in all cases.  There's
obviously no way to know when the browser actually came up and jumped
to the destination page, which is why these files are left behind,
with an occasional (`random'ly chosen) cleanup of files that look
sufficiently old.  (And BTW, it looks like the gnome browser starter
thing is doing the same thing, which would make the same hack useful
there too.)
