Assuming LaTeX support in kopete is generally used to typeset math, surprisingly few math-related packages are included in the LaTeX preamble.

As a result, many reasonably common equations cannot be displayed, but worse, they are simply displayed incorrectly (no error or warning is issued)

an example could be: $$\binom{n}{2}^2$$ which is displayed like so: http://users.skumleren.net/cers/kopetex/before.png
instead of the the intended:
http://users.skumleren.net/cers/kopetex/after.png

The converter is (on my system) placed here:
/usr/kde/3.5/bin/kopete_latexconvert.sh
and I will attach a patch that will fix most of these problems.

I understand that one should not include too many strange packages, but I think it would be smart to at least include the most commonly used ones.

By the way, it isn't sufficient to correct this problem on only the senders side, as it is converted both at sender and receiver side. ( This is related to bug#107094 http://bugs.kde.org/show_bug.cgi?id=107094 )
