Indeed. Very strange. And I even have it installed. But ff3 can
print to lpr only when I install the compiled-from-source version
of 2.10 (in /usr/local). As soon as I uninstall it, lpr printing
on ff3 becomes unavailable.

/usr/lib/gtk-2.0 (the Debian version) contains subdirectories:
   2.10.0  2.2.0  2.4.0  include  modules

No 2.12.0! I don't understand this numbering system.

/usr/local/lib/gtk-2.0 contains: 2.10.0  2.2.0  2.4.0  include
(no "modules", but the same version numbers).

The real difference is probably to be found here: the Sid version has:

jws@vega:~$ ls -alG /usr/lib/gtk-2.0/2.10.0/printbackends/
total 104
drwxr-xr-x 2 root  4096 2008-06-09 17:32 .
drwxr-xr-x 9 root  4096 2007-04-15 14:58 ..

-rw-r--r-- 1 root 11140 2008-06-07 11:16 libprintbackend-test.so

While the compiled-from-source version (from gtk.org) has:

jws@vega:~$ ls -alG /usr/local/lib/gtk-2.0/2.10.0/printbackends/
total 92
drwxr-sr-x 2 root  4096 2008-07-06 21:26 .

-rwxr-xr-x 1 root 34034 2008-07-06 21:26 libprintbackend-lpr.so

I compiled by just "./configure", "make", without setting any
options. So by default gtk does not have a cups print backend,
only "lpr" and "file" (when compiled on a cups-less system, I
presume). The Debian version has "lpr" and "file", as well as
"cups" and something called "test".

Maybe you can explain these findings. Anyway it seems that the bug
is not in ff3 but in libgtk2.0-0.
