I do have a workaround for that. Enable display of labels in comments 
using reftex-label-menu-flags. Then just put a comment with the same 
label name somewhere near your actual label (the one reftex can't find).

I just did it for lstlistings like this:
%\label{lst:mylisting}
\begin{lstlisting}[caption={Some caption},label=lst:mylisting]
Some code
\end{lstlisting}

Cheers,
Martin
