[needs-packaging] gstreamer crashes several applications

Hi i got several issues using the gstreamer, once i installed Pitivi it did corrupt my installation of rhythmbox, once I uninstalled Pitivi, problem remained rhythmbox misses plugin : MPEG-4 AAC Decoder, and the software finds only the gstreamer for that.

Once it is installed the gstreamer0.10-plugins-bad crashes several applications such as, Pidgin, Rhythmbox and Software Center. The console gives these errors

Is there an alternative to the gstreamer ?
