"Couldn't play song. Skipped ahead." is displayed by Google Music when playing track

[kelveden]

Nuvola Player: 2.0.3
OS: Arch Linux 3.9.8-1 x86_64

Steps to reproduce:
1) Switch to Google Play Music service
2) Attempt to play a track or album from library

Expected:
Track plays

Actual:
Attempt to play a track fails with the message (from the Google Music UI itself by the look of things) "Couldn't play song. Skipped ahead".

Notes:
* My machine sits behind a corporate proxy server and firewall.

* Playing a track via Google Music in a browser (Firefox 22.0 or Chromium 28.0.1500.52) on the same machine works.

* I have taken a look at the HTTP traffic from Nuvola when playing a track via a web proxy (Charles) and can see the HTTP requests to Google music - they all look ok to the naked eye. However, Charles does state that "Client closed connection before receiving entire response" but apart from that they look like the request/response below:

Thanks for taking the time to report this bug. However, I need more
information to investigate it further.

Assuming Arch Linux has libwebkitgtk3 with gstreamer 1.0 backend,
could you post output of following commands? You need a MP3 audio file
for the second command, I'll call it "/path/to/song.mp3".

gst-inspect-1.0 | grep mp3

GST_DEBUG="*:3,GST_ELEMENT_FACTORY:4,GST_PLUGIN_LOADING:4" \
gst-launch-1.0 playbin uri="file:///path/to/song.mp3"

  status incomplete

Thanks for the reply Jiri. The short story is that with your suggestions from above I was able to solve the problem - I was missing the gstreamer "ugly" plugin.

So thanks for the help! (The long version is below if you're interested...)

I can't find a way to confirm 100% that I have libwebkitgtk3 installed but all libwebkit*.so files on my machine are libwebkit*-3.0.so files. So, I assume I do. Here's the output from the first command:

----------------------

typefindfunctions: application/x-id3v2: mp3, mp2, mp1, mpga, ogg, flac, tta
typefindfunctions: application/x-id3v1: mp3, mp2, mp1, mpga, ogg, flac, tta
typefindfunctions: application/x-apetag: mp3, ape, mpc, wv
typefindfunctions: audio/mpeg: mp3, mp2, mp1, mpga

----------------------

And here's the output from the other command:

So for those Arch users stumbling across this bug here is the short solution:

pacman -S gst-plugins-base gst-plugins-good gst-plugins-ugly

I think Arch Linux users would have life easier if the package would
be better maintained and have these packages as dependencies...

I've added link to FAQ #2277 to the bug reporting tutorial.

Agreed. Have added comments as such against the Arch AUR package: https://aur.archlinux.org/packages.php?ID=58166.

FAQ is a good idea too!
