TUI mode is messed up

I see these problems in TUI mode: source window shows lines not in the 
right order.  This happens after several next/up/down commands. Also, 
when the program begins to print something to the standard output, TUI 
window gets scrolled out from the screen, and also lines coming from 
debugged program are shifted to the right, like they didn't wrap around 
properly.

Is TUI broken? Maybe it works only in some terminals and not others? I 
use kde konsole. Or maybe my FreeBSD port of gdb is broken?

gdb-7.6.2
