Bug#801136: mpd-sima: Troublesome with proxies

[Geoff]

Hi Chris,

Thanks very much for your report :)

Two issues then :

[packaging] http proxies env. var should be exposed when using
systemd/SystV.

[upstream] the http client should actually use them ^^
The http client bug was forwarded upstream, the issue is
identified/nearly fixed. Python requests is actually not honoring
HTTP_PROXY because of the use of the lower level API in the http client
which in turn is not propagating environment variables…

I'll try to fix this as soon as I can (I'm also the upstream developer).

Thanks again.
Geoff
