If it's an ncurses bug, then that should be either repeatable by setting
the same environment, e.g., TERM and the locale stuff, same screen size
and capturing the output using 'script'.  It simplifies things to 
eliminate as many variables (and reduce the logsize, of course).

Occasionally I do find some problem using valgrind, e.g., an uninitialized 
variable.

If you make the good/bad configurations "identical", and the trace is the
the same on both, but the typescript (from script) is different, that 
still gives some clues, since the trace doesn't cover everything.

Ultimately all that matters is what goes to the screen.  The trace (for 
the TRACE_UPDATE flag) shows a picture of the before/after each time a
refresh is done on a window.  While it's useful, that part can make the 
trace files very large.

sorry (was busy).
