## Debug log

http://paste.kodi.tv/bonaruvaze

Start in resources/lib/KodiHelper.py at build_profiles_listing and the unescaped_profile_name assignment shown in the traceback. Reproduce the profile-listing path with a name containing non-ASCII characters and inspect how Python 2 HTMLParser.unescape handles enc_profile_name. Done means the profile listing no longer raises UnicodeDecodeError for such names.
