I am experiencing the same problem too (version 1.1.5 on Ubuntu 14.04.3 LTS).

My playlist (.m3u) contained East Asian Characters encoded in UTF-8. Log file revealed similar error message. What worse, it made other previously loaded playlist disappeared. I had to remove the playlist file crashing the system and rescan (minidlnad -R).

The MP3 files named in UTF-8 are, however, they can be corrected searched and played with other tags e.g. album / artist.
