This does look like TeX is seeing \verb while it is processing the 
argument of a previous command. Can you check first that there aren't 
any missing close-curly-braces anywhere before the \verb?

Hyperref makes LOTS of very deep-seated changes to LaTeX. For this 
reason it should always be the last package you load.

Can you try moving your \usepackage{hyperref} to after all other 
\usepackage commands and see if that helps.

You might also try using a different delimiter, eg \verb`Op` or \verb+Op+
