AUCTeX 11.90 does some additions to `ispell-tex-skip-alists' in order to
skip more macro arguments and environments; they are all in
tex-ispell.el. The scenario you describe is strange, and I can't tell
why it happens.

I'm not on OpenSuse and don't use ispell (I use Hunspell), but I can
offer some possibilities you can try:
1) Try $\sigma$ contradition -- it has the same effect within LaTeX
2) Try \( \sigma \) contradition -- note the spaces around \sigma; same
effect, but ugly
3) Eval the form in verbatim environment below and run ispell again:
--8<---------------cut here---------------start------------->8---
\documentclass{article}
\begin{document}
\begin{verbatim}
(TeX-ispell-skip-setcar
'(("\\\\(" . "\\\\)")))
\end{verbatim}
\(\sigma\) contradition
$\sigma$ contradition
\end{document}
--8<---------------cut here---------------end--------------->8---
If it works, I can add it to tex-ispell.el.
4) Disable the new feature by setting `TeX-ispell-extend-skip-list' to
nil.
HTH.
