[Question reordered.]

Yes it is.
$ dpkg -l texlive-science-doc # shows 2009-10
$ gunzip /usr/share/doc/texlive-doc/latex/objectz/ozguide.dvi.gz
gzip: /usr/share/doc/texlive-doc/latex/objectz/ozguide.dvi.gz: Too many levels of symbolic links

Since `gunzip` fails it is no bug in Evince.

How can I check that? I am using an Ext3 file system.

There is enough space as far as I can tell.
Ok, searching for »gzip "Too many levels of symbolic links"« on the WWW
gave among others the following results [1][2][3][4].
Looking at the symlink again
$ ls -l /usr/share/doc/texlive-doc/latex/objectz/ozguide.dvi.gz
lrwxrwxrwx 1 root root 57 25. Sep 09:48 /usr/share/doc/texlive-doc/latex/objectz/ozguide.dvi.gz -> ../../../texlive-science-doc/latex/objectz/ozguide.dvi.gz
I do *not* see how it could be pointing to itself.
I did some more tests and it happens with all links of *.*.gz files.
$ ls -l /usr/share/doc/texlive-doc/latex/amsmath/diffs-m.txt.gz
lrwxrwxrwx 1 root root 60 25. Sep 09:46 /usr/share/doc/texlive-doc/latex/amsmath/diffs-m.txt.gz -> ../../../texlive-latex-base-doc/latex/amsmath/diffs-m.txt.gz
$ gunzip /usr/share/doc/texlive-doc/latex/amsmath/diffs-m.txt.gz
gzip: /usr/share/doc/texlive-doc/latex/amsmath/diffs-m.txt.gz: Too many levels of symbolic links
So it looks like it is either a problem with `gzip` or something on my
system is screwed up. Reinstalling the package did not help by the way.
Thanks,
Paul
