I found an mp3 file that makes cmus stop responding to user input, as soon as the file is being played. Except for Ctrl-C (which gives the 'type :quit ...' message) nothing seems to get processed. Also the cpu usage increases.

It also messes with one line of the ui, when being played. The title seems to contain a 'M- '.

because of copyright reasons I uploaded the result of
$ head -c 40k <music.mp3 >head.txt.
