404 output doesn't obey hug.defaults.output_format

[akaihola]

I'm setting

hug.defaults.output_format = hug.output_format.accept(
    {'application/json': hug.output_format.json,
     'text/yaml': hug_yaml.output_format.yaml,
     'application/x-yaml': hug_yaml.output_format.yaml},
    default=hug_yaml.output_format.yaml)

All my API endpoints now return YAML by default. The output format for responses also correctly changes according to the Accept: header.

However, the API description included in 404 responses is still always JSON, no matter whether I omit or include an Accept: header.

This is fixed in Release 2.4.6: https://github.com/timothycrosley/hug/releases/tag/2.4.6

Thanks!
