This file processes ok here; also, your bug is not so much related to
headers but more to some kind of \_ expansion In what path are your
graphics?
it breaks on 2004.8.14 as well on live.contextgarden.net
Graphics (cow.pdf) is in /opt/local/texmf/tex/context/sample
If the two graphics are not on the same page, the error dissapears.
The reproduction of the error is very sensitive to layout changes.
the problem occurs in the output routine (when the page is built); some tracing all learns that while flushing the fig box takes place, the meaning of textunderscore is changed; so we need to restore this before hand; actually this problem should be solved differently, i.e. no redefinition at all; the problem is that findinf good solutions is not that easy because of moments of expansion
fix (in core-fig.tex:)

Hello Hans, [...] fix (in core-fig.tex:) solves the problem here.

[NTG-context] Re: error with _ in header?
Hi Hans, thanks for your fix. It solves the problem. Will this fix be included in future Context releases? I am still confused why the content of the document directory had an impact on the output routine. (The problem disappeared after I had removed additional *.png files in the document directory. When I copied the superflous images into there again the problem reappeard.) I accept that computing in general and Context in special is kind of an empirical secret science. ;-) Thanks again, --Stefan ___ ntg-context mailing list [EMAIL PROTECTED] http://www.ntg.nl/mailman/listinfo/ntg-context

Hi Patrick,
first I want to say that I already spent several hours on that problem
and was happy to reduce the file size to 5215 Bytes. Of course I could
have done further but I thought that the file is now handy enough for
debugging. (I do not know how TeX code is debugged and what tools are
available for that task.)
btw: with the error related to other files in the directory: did you
run texutil --purgeall for testing?
Yes, I removed all temporary files. But the strange behaviour remains:
when all images except that of the used external figure are removed then
the error disappears.

Hello Stefan,
I prunned the example to investigate the situation further. Now I have
only two pages.
Well, how do you think anybody should be able to debug what you have
done with all the stuff in your document?
You should definitely try to reduce the file size to a minimum,
otherwise it is hard to track the problem down.
minimum is far from 150 kb. And please avoid external figures if
possible (there is cow.pdf hacker.jpg and mill.png for download, so
we can all have the same figures to experiment with).
Please do your homework yourself next time:

Is the minimal test file I've come up with. Perhaps now it is easier
for Hans to track down the problem. The error message is:

[NTG-context] Re: error with _ in header?
Hi, [...] (I do not know how TeX code is debugged and what tools are available for that task.) There are no tools for problems like yours. So it is very important to have a minimum (non-) working file file. btw: with the error related to other files in the directory: did you run texutil --purgeall for testing? Yes, I removed all temporary files. But the strange behaviour remains: when all images except that of the used external figure are removed then the error disappears. This is strange, I cannot reproduce the bug here. But let us wait to see if Hans has anything to say about the error file.
