Hi Norbert,
I don't know why this happens, but I see other problems with
compressed PDF files. I suppose that texdoc de-compresses the file
supposed to be displayed in a temporary directory before a viewer is
started. Some PDF files contain hyperlinks to other PDF files on the
file system. Since hyperlinks are evaluated by the viewer, I suppose
that they don't work.
You can try "texdoc vntex" and click on one of the blue links on the
first page. Are those hyperlinks supported by Debian?
BTW, since TL enables object stream compression by default now, I
don't expect a significant decrease in file size when compressing them
again.
Regards,
Reinhard

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
