Since Ubuntu jaunty RC, when I compile xelatex documents, the math is not printed properly. In the file xelatex_minimal_test.tex I get the "sum" sign not printed when compiling with xelatex under jaunty.
To reproduce:
1. Under jaunty, do: xelatex xelatex_minimal_test.tex
2. Look at PDF file. The text (with the "é" non-ASCII letter) is printed but not the math.
I have package texlive-xetex 2007.dfsg.2-4ubuntu2
When doing the same under interpid, I got the sum sign printed.
This is xelatex output when compiling the file:
This is XeTeXk, Version 3.141592-2.2-0.996-patch2 (Web2C 7.5.6)
%&-line parsing enabled.

Transcript written on xelatex_minimal_test.log.
I can confirm this bug on Jaunty (9.04); it was not present in Hardy (8.04).
There is a fix for this on the debian-bugs-list:
http://<email address hidden>
I have applied that fix to my system and mathematical symbols are now produced correctly with XeLaTeX.
In brief, edit the configuration file: /etc/texmf/
Comment the line "f pdftex.map" by adding a percent symbol at the beginning of the line.
Uncomment the line "f dvipdfm.map" by removing the percent symbol.
Save and run xelatex again.
