[cups.bugs] [MOD] STR #1876: All-white page on https://server:631/admin/ login

[STR New]

Having got cups 1.2.2 working on our Solaris 8 printserver, though with a
few odd problems reported elsewhere, I decided that the reason that I'd
had trouble was my choice of a less-than-common operating system platform,
surely most people have CUPS installed on Linux. So, I stopped the
experimental CUPS scheduler on my Solaris printserver and chose a
Slackware Linux 10.1 compute server (on the same subnet as the Solaris
system, which is the same subnet our Linux desktop clients are on also). I
then built CUPS 1.2.2 from source and installed it - taking care that none
of the install overwrote anything already installed as part of the
Slackware distribution (summary follows, see attached file typescript for
the full story):

# ../configure --prefix=/lib/cups-1.2.2
--localstatedir=/var/spool/cups-1.2.2
# make
-- I edited Makefile here to remove line 33, which adds PHPDIR to the list
of install directories, as I didn't want to pollute our PHP installation.
# make install
# /etc/rc.d/init.d/cups start
cups: started scheduler.
# cd /var/spool/cups-1.2.2/log/cups
# cat error_log
....

All seems well. One difference from my Solaris install is that that did
not build with SSL. So, when I browsed http://server:631/printers/ and
clicked on the 'Start printer' button of the printer I've been using to
test with (an HP LaserJet 8150dtn), I see the message:

426 Upgrade Required
You must access this page using the URL
https://server:631/admin/?op=start-printer&printer_name=printer

and a dialogue box asking me to login as the CUPS administrator. I do so
by logging in as 'root' with the system's root password, and get a
completely white web page. Pressing reload only gets me the dialogue box
again. If I type a nonsense password, I see:

401 Unauthorized
Enter your username and password or the root password to access this page.

I can't manage the installation via the web interface!

What gives? I attach the build log of my installation.
