Bug#904000: audacious: Opening URL fails

[lili]

Source: audacious
Severity: grave
Justification: renders package unusable

Dear Maintainer,

-- System Information:
Debian Release: 9.4
APT prefers stable
APT policy: (500, 'stable')
Architecture: i386 (i686)

Kernel: Linux 4.9.0-3-686-pae (SMP w/1 CPU core)
Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en (charmap=UTF-8)
Shell: /bin/sh linked to /bin/dash
Init: systemd (via /run/systemd/system)

Audacious suddendly does no more acctept standard URLs like this:
http://servername:port/file.

In my case it was "http://relay.publicdomainproject.org:80/modern_jazz.aac".

This worked fine for a while - same on all other media players,
because it's a real trivial pointer to some source.

Then I just checked out the audacious features, playing around all the
multiple options. I really can not remember what I tried all - but
suddendly the above mentioned URL failes with the error
message "Unknown URI scheme".

How can this be???

I "purged" audacious with the apt-tool, then reinstalled it,
but the problem persists.
