Mapping metadata with avconv does not work

The way I understand man avconv (version 9.16-6:9.16-0ubuntu0.14.04.1), the following command should convert input.ogg to output.mp3 and carry over metadata: avconv -i input.ogg -map_metadata 0 output.mp3 It does not, however; ogginfo clearly shows the information (artist, album, title, ...) in input.ogg and id3info confirms that output.mp3 has empty (ID3) tags. The same happens when converting ogg to flac, or (presumably) any combination of the formats. Is my understanding of -map_metadata wrong? Is there a way to convert between formats and keep tags (without hardcoding like [this](https://unix.stackexchange.com/a/10186/17409)) ?
