...looking at the trace, here's is happening:

ncmpc creates a 2-line window.
it doesn't enable scrolling in that window.
it writes the multibyte character string to the second line of the window.

ncurses gets to the end of the line, with one cell available, for a 2-cell 
character.  Since scrolling is disabled (by default), it writes the 
wrapped character onto the same line.

(addstr should have stopped in this case, rather than wrapping - will 
see...)
