This is not really a LyX bug, but rather the kind of things that
happen when using ugly workarounds like the one I suggested... What
happens is that the math editor will output pi as \(\pi\) and the
command \( is `fragile', meaning that it cannot go like that in text
which will move to table of contents or similar (for obscure and
technical reasons I do not fully understand). The solution in this
case is to add \protect just before the formula, and LyX does that in
section headers. However, in the present case, LyX has no way to know
that \pi is in a `moving' argument, and the magical \protect is not
added.
