Pedro, 
 I have an issue when installing the -dbgsym files.

gstreamer0.10-pulseaudio only has 

$ aptitude search gstreamer0.10-pulseaudio
i   gstreamer0.10-pulseaudio                 - GStreamer plugin for PulseAudio                   
p   gstreamer0.10-pulseaudio-dbgsym          - debug symbols for package gstreamer0.10-pulseaudio

Just trying for gstreamer0.10 gets me this 

$ aptitude search gstreamer0.10-db*
p   gstreamer0.10-doc                        - GStreamer core documentation and manuals          
p   libgstreamer0.10-dev                     - GStreamer core development files                  
p   libgstreamer0.10-dev-dbgsym              - debug symbols for package libgstreamer0.10-dev  

same for gstreamer0.10-alsa

$ aptitude search gstreamer0.10-alsa
i   gstreamer0.10-alsa                       - GStreamer plugin for ALSA                         
p   gstreamer0.10-alsa-dbgsym                - debug symbols for package gstreamer0.10-alsa  

The moot problem here seems to be that gnome has only a gnome-dbg 

$ sudo aptitude install gstreamer0.10-plugins-base-dbgsym gstreamer0.10-plugins-good-dbgsym
