[tex-live] hyperref 6.79n breaks xetex's (xdvipdfmx) ability to set proper page dimensions (and overrides page dimensions on pdftex)

Hi Heiko and all,

[first is the xetex-related part of bug report, then follows the
pdftex-related part]

when using hyperref with unicode option, I'm not able to set the proper
page dimensions.

Here is a minimal working example which demonstrates the problem:

This is a test.

when running "xelatex test.tex", i see the following few last lines on

[1] (./test.aux)
** WARNING ** Failed to convert input string to UTF16...
Output written on test.pdf (1 page).
Transcript written on test.log.

(the WARNING is actually produced by xdvipdfmx, rather than by xetex itself;
the \pdfpagewidth and \pdfpageheight primitives are working in xetex,
and i used them rather than the geometry package to make an example
simpler to debug.)

when i then run "pdfinfo test.pdf", i get:

$ pdfinfo test.pdf 
Title:          test
Creator:        LaTeX with hyperref package
Producer:       xdvipdfmx (0.7.7)
CreationDate:   Mon Dec 14 04:04:07 2009
Tagged:         no
Pages:          1

Page size:      612 x 792 pts (letter)
File size:      3087 bytes

PDF version:    1.4

Notice that the page size is wrong.

If i comment out the line which calls the hyperref package, i get no
warning, and the pdfinfo shows the expected page size:

$ pdfinfo test.pdf 
Creator:         XeTeX output 2009.12.14:0405
Producer:       xdvipdfmx (0.7.7)

I'm using current subversion snapshot of texlive (same behavior happens in
the released TeX Live 2009):

XeTeX 3.1415926-2.2-0.9995.2 (TeX Live 2009)
pdfTeX 3.1415926-1.40.10-2.2 (TeX Live 2009)
hyperref 6.79n

is this a bug in hyperref (e.g. it produces some malformed UTF16 string
which xdvipdfmx can't handle) or in xdvipdfmx?

Now, the pdftex-related part of the bug report.

If I uncomment the "\showthe\pdfpagewidth" line, i see that the
\pdfpagewidth gets reset after the \begin{document}:

pdflatex shows:
> 614.295pt.

if i comment out hyperref usage, i get the expected result:
> 301.125pt.

in xetex, I'm always getting the 301.125pt result, regardless of
presence of hyperref; but nevertheless because of the WARNING by
xdvipdfmx, the page dimensions appear wrong when using hyperref.
