The reason for the error is that a figure is a moving argument and fragile arguments like ref have to be protected from expanding. So there must be a \ref before the \ref:

\caption{another example of figure \protect\ref{example}}

More information can be found in Lamports LaTeX book on page 59.

I would like to thank Nick Dokos (nick@osf.org) and Bernd Raichle
