Ok, after calming down (a bit) ;-), and sort of getting a more
reliable environment, I get this message with screen-256color:

"TERMCAP", line 19, col 1, terminal 'SC': Missing separator

Screen's termcap dump looks like this:

Currently I work around this by militantly disabling TERMCAP for
everything -- mplayer is missing a termcap entry then, but so far
that's ok for my purposes. Still, that's very hackish.

I also have to configure the program calls in screenrc like so:

bind E screen -t mutt 3 env TERMCAP= mutt

instead of simply:

bind E screen 3 mutt
