This should be in a different patch, one that is related just to
dump_trace, i.e. if -D, aka dump_trace (right?) is enabled, then
probably we won't be initializing the TUI/GUI, no?
So having a patch that deals just with conversions of fprintf ->
pr_{err,etc} and another that deals with dump_trace related seems to be
the best course of action.
