Comment 7 for bug 1011056

I upgraded to gnome-control-center 1:3.4.2-0ubuntu4, but I still have the display manager problem:

awm10@awm10-Lemur-Ultra:~$ gnome-control-center
/usr/lib/control-center-1/panels/libdisplay.so: undefined symbol: gnome_rr_labeler_get_color_for_output
Failed to load module: /usr/lib/control-center-1/panels/libdisplay.so
awm10@awm10-Lemur-Ultra:~$ gnome-control-center -v

^C

I just checked the main repository, and I have the latest version of everything else too. I don't know if it's related, but VLC has a similar problem (similar in my opinion because I think they're both Python-GTK, please correct me if I'm wrong):

awm10@awm10-Lemur-Ultra:~$ vlc

Hope that helps for something.
