Ok, somehow your copy of config-paper.ps got messed up, that can happen.
I have no changed tl-paper (the script) in a way that when *setting*
a paper size, it *first* unsets TEXFMVAR and TEXMFSYSVAR. By this
the normal code with kpsewhich in TLPaper.pm will find the
copy originally distributed in TeX Live (/u/s/texlive/texmf-dist),
*or*, if the sysadm changed something, a copy in TEXMFSYSCONFIG,
but *NOT* (!) the one we have created with tl-paper in TEXMFSYSVAR.
THis way, we are sure that the format is correct while reading in
the current papers and creating a new correct one in TEXMFSYSVAR.
THe sysadmin still has the option to add his own copy of config-paper.ps
in /etc/texmf/dvips/config/ and adjust the paper sizes or whatever,
but he has to care for the syntactic correctness. Something that we anyway
require ;-)
The patch is quite simple:
diff --git a/texlive-base/debian/tl-paper b/texlive-base/debian/tl-paper
index e8f3ec9..7fc5223 100644

I did some experiments with deliberately scramlbing the config-paper.ps
file, and it worked.
Hope you agree that this is a solution to the problem.
