In Konsole, when I select Settings/Font/Linux, the following error message shows up: Font `-misc-console-medium-r-normal--16-160-72-72-c-160-iso10646-1' not found. Check README.linux.console for help. "Linux" font is my favourite font and the it does exist in the system. If I select "console" font from the Settings/Font/Custom menu, then I have the font, but it is not capable of showing drawing chars (eg. what midnight commander, mutt, make menuconfig, etc uses). The font itself can do that (it does this in a real console), and in the past I was able to use it in konsole without the above problem.
Did some research on this problem. The font is located in /usr/kde/3/share/fonts. I added this to all relevant an possibly non relevant:) paths where fonts are searched. No avail. Still cannot be switched by selecting Linux in the konsole font menu. In the custom font menu it can be selected, but garbage chars are displayed instead the line-drawing graphical ones when mc and mutt is used. I found a konsole bug on the konsole-dev list which associates this problem with qt-3.05 not picking the right character to test the line drawing char capability of a font (apparently the "console" font does not have this char what qt-3.05 picks). Qt-3.04 claimed to be working, but it is not in portage and I do not want to mess with my kde on a production machine...

I advise you to test qt 3.1.0. Even if it doesn't work it's better to look for solutions against it than against an older version. We're going to mark it stable in a few days anyway and eveyone will upgrade. And it is freely interchangeable with qt 3.0.5 in either direction, your kde won't be affected and you can even downgrade again if you like.
Emerging qt 3.1 and remerging kdebase solved all the problems: now the "Linux" font can be selected without problems, and "graphical" line drawing characters work as expected in mc and mutt.
