Quoting Samium Gromoff (_deepfire@feelingofgreen.ru):
The local consensus on #lisp (roughly, lichtblau and me) was that it will do good to have an issue tracker for McCLIM.
Well, all bug tracker software stinks and is a hassle to work with.
That said, I have already lost track of the few gtkairo bugs reported recently, so I am in favour of putting them into a bug tracker. Better a bug tracker that gets ignored than mailing list postings that get ignored and forgotten.
I volunteer to set up/help setting up one, as well as semi-regularly look through the issues posted there.
Whoever "owns" the McCLIM project could just ask for trac to be enabled on cl.net. Then you get to put your bug reports into it.
