I've just checked that this issue is also present in cups-1.4.0 as
well, not only cups-1.3.11. I haven't checked 1.5 yet.

I'm looking into implementing reference count, but it seems like there
are lots of places when mimeType() is being called, and it's sometimes
hard to figure out what exactly is happening with the pointer -- is it
stored in another struct or not, and when is the right time to free
it. Do you have any advice on this?
