Followup-For: Bug #801136
Package: mpd-sima
Tags: patch, confirmed

Here is a patch, it should merge available HTTPS?_PROXIES variables.
I will patch the debian package if it takes too long to release the next
upstream version including this fix.

I haven't fully tested the solution yet.
Don't hesitate to give it a try, the patch should merge fine on 0.13.

I'll have a look at the packaging part later.
