Even simpler:

\begin{description}
\item [$]$]blah
\end{description}

LaTeX gets confused. The appropriate entry from the log file:

l.20 \item [$]
              $]blah\end{description}
I've deleted a group-closing symbol because it seems to be
spurious, as in `$x}$'. But perhaps the } is legitimate and
you forgot something else, as in `\hbox{$x}'. In such cases
the way to recover is to insert both the forgotten and the
deleted material, e.g., by typing `I$}'.


! LaTeX Error: Something's wrong--perhaps a missing \item.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.

Personally, I think you've been unfortunate, but LyX's mathed editor 
has never prevented you from generating incorrect latex, nor could it 
without being a fully fledged latex compiler.

Just my 2 pennies of opinion of course.
