Dennis,
It sounds as though you have not put  a dot in "Perform a Profile to Profile Conversion" near the bottom of the dialogue.
see attached screen snap.
It would have printed ok because Q will convert from the image profile to the printer profile during the printing process.
Also you do not necessarily have to
You can do this from the Convert dialogue using "Add to" filters
Terry.

I'm a bit confused about the profile to profile conversion. I normally print either to a printer or to file applying the appropriate printer profile. But this time I want to print some raw images to sRGB to give to someone who wouldn't understand about the difference between colour spaces.

So I have the raw conversion set up as Adobe RGB as the working space. Does this mean that I have to specify adobe RGB as the input profile for the conversion, and sRGB as the output?

I note in Terry's example above that he has <input> as the input profile. Does that do the same thing?  i.e. take whatever the input profile of the particular image happens to be. So if I had a mixture of images with different input profiles in the queue it would always "do the right thing"?

I can't find any description of <input> in the help (though I'm sure its there somewhere:-)

Would I get equivalent results by using the print to email/web and setting the resolution to be something reasonable?

Thanks Terry. That works just fine.
