Parole audio player reports this error:
"A text/uri-list decoder plugin is required to play this stream, but not installed."

I searched gstreamer support for troubleshooting this problem. This provides the following support recommendations:

1) List plugins installed, 
Documentation:
[url=http://gstreamer.freedesktop.org/data/doc/gstreamer/head/faq/html/chapter-using.html#using-gst-inspect]
"To do this you use the gst-inspect command-line tool, which comes standard with GStreamer. Invoked without any arguments,"
   $ gst-inspect

This step outputs this related plugin, "text/uri-list:ram". From this I assume ram is supported. I want to add support for m3u. The next page continues with more troubleshooting information.

2) Check that I have a plugin that I am supposed to have from (1) above:
Documentation:
[url=http://gstreamer.freedesktop.org/data/doc/gstreamer/head/faq/html/chapter-troubleshooting.html]
"Q: Some application is telling me that I am missing a plug-in. What do I do ?
A: Well, start by checking if you really are missing the plug-in."
   $ gst-inspect (plug-in)
  
3) Typing various permutations of the output from (1) using the instructions in (2):
# gst-inspect text/uri-list
text/uri-list: a typefind function
[root@xtiansimonibm Xtian]# gst-inspect text/uri-list:ram
No such element or plugin 'text/uri-list:ram'
[root@xtiansimonibm Xtian]# gst-inspect text/uri-list: ram
No such element or plugin 'ram'
[root@xtiansimonibm Xtian]# gst-inspect ram
No such element or plugin 'ram'

Producing what appears to me as a false negative. Certainly all command line tools only output based on what you put in. At the very least these instructions should communicate how to create positive test output.
