mailcap file is being ignored

[ztx-lyghters]

I have this set in my conf.py:
MAILCAP_FILE = os.path.expanduser("~/.config/mailcap")

My mailcap file has only this line:
audio/*; vlc "%s" &

Despite this, mp3 audio files from dialogs/groups are being opened with mpv.

Yeah same issue here - mailcap entries seem to be irrelevant. Seems to be using xdg-open though, which means you can set per-mime-type defaults with xdg-mime. Should function as a workaround for now, although you may need to make your own .desktop entries depending on the setup you want.
