This problem occurs because xterm takes the termcap entry and puts it into
the TERMCAP environment variable. Unfortunately, it gets a truncated
entry, with certain capabilities missing. Thus, the curses code thinks
that your terminal can't do bold or reverse or underline (or whatever).
The wordround is to unset TERMCAP in your environment. I was thinking
that the fix is to stop xterm from generating a TERMCAP environment
variable in the first place.

Hmm, strange. Do you have termcap.src,v 1.57? There was a problem with
the "default colours" sequence for xterm on previous versions. Or, it
may be another symptom of the truncated TERMCAP. Does it still do this
if you unset TERMCAP?

This changed because the termcap entries that we used to ship don't contain
the extra attributes that are needed for colour and other enhancements.
