Description of problem:
SELinux prevents Fluendo's mp3 codec from working. An alert will show up every time an application tries to use it.

Version-Release number of selected component (if applicable):
codeina-0.10.1-9.fc10 

How reproducible: always

Steps to Reproduce:
1. Start rhythmbox
2. Play an mp3 file
or
1. Start totem
2. Play an mp3 file or video with mp3 audio
or
1. Play an mp3 from console with gst-launch:
$ gst-launch filesrc location=music.mp3 ! flump3dec ! pulsesink
  
Actual results:
Silence.
A SELinux alert pops up and, in the case of gst-launch, a console message will show up:

(gst-launch-0.10:3841): GStreamer-WARNING **: Failed to load plugin '/home/user/.gstreamer-0.10/plugins/libgstflump3dec.so': /home/user/.gstreamer-0.10/plugins/libgstflump3dec.so: cannot enable executable stack as shared object requires: Permission denied

The SELinux alert states:
SELinux is preventing gst-launch-0.10 from making the program stack executable. 

Expected results:
No alerts and proper playback.

Additional info:
Totem and Rhythmbox will fall back to ffmpeg if gstreamer-ffmpeg installed.
I'm not sure but this bug looks like regression:
