Ubuntu 8.04 Hardy Heron default versions
texmacs 1.0.6.11-2
maxima 5.13.0-3ubuntu1

<\output>
  \\2latex:

Disappointing... Ubuntu seems to be wrong choice for scientific 
applications.
I edit /usr/lib/texmacs/TeXmacs/bin/tm_maxima to launch 
texmacs-maxima-5.11.0.lisp for maxima-5.13 and type

3*sqrt(2)/2

spurious brackets that can be written to .tm file but can't be read 
correctly. .scm serves as workaround.

The .tm file is attached

texmacs_1.0.7-2_i386.deb + texmacs-common_1.0.7-2_all.deb built from the 
debian source package files deals with "3*sqrt(2)/2" fine, however it 
can't read the corrupted file produced by 1.0.6. I'm happy with this 
solution.
