Rhythmbox plugin installer can't find plugin required to play mp3

[Ahmed Mamdouh Taher]

when I try to play any mp3 file, Rhythmbox searches for plug in, but it cannot find it and i get this error message.

Required plugin could not be found

Python (v2.7) requires to install plugins to play media files of the following type: MPEG-1 Layer 3 (MP3) decoder

Sorry, I guess it is sessioninstaller being used for this now.
Anyway, I was not able to reproduce the error. I uninstalled the mp3 plugin(s), and I got the the same dialog, but it was able to find/install the appropriate plugin.
Would it be possible for you to start rhythmbox from the terminal and attempt to play mp3? Please attach the terminal output.

Also, if you just want to work around the error, you can manually install restricted format support: https://help.ubuntu.com/community/RestrictedFormats#Terminal_Install

Thank you. I made this work around before i check the terminal output and it works now. So I will not be able to get the same terminal output, when I had the error.
