Hi Dave!

you're right about the bug: it takes place when no multiple option is a
string.

I've just fixed this bug (and added a test in the test suite)

I was working on the next release 2.17 that can be found here
temporarily (release candidate)

http://rap.dsi.unifi.it/~bettini/gengetopt-2.17rc.tar.gz

and this includes this fix.

Hope to hear from you soon!
thanks again for the feedback!
cheers
        Lorenzo
