Oh, yes, those nasty keyval thingies.  Once I tried to get listings
working and failed just like you.

Could you try the attached patch?  It's against the reftex version in
the current emacs trunk, but those files don't change that often, so
probably it'll apply against the latest release as well.

Ah, and one restriction: You have to write labels like so

  [..., label={tab:foo}, ...]

that is, no spaces around the =, and the {} are mandatory.  That could
probably be relaxed a bit, but maybe you'd get false positives then...

I tried it with the attached tex file and it seems to work for ctable
and listings (which I added, but the context isn't that good).

Bye,
Tassilo
