Comment 2 for bug 1248735

That everything seems to load correctly but not talk to each other suggests that the problem may be with the profiles or with name lookup.
Looking at the logs they all seem to be using the profile "Default" but you might want to check to make sure.
The other likely cause is that the name lookup isn't working properly - Check that your hostname responds to a lookup (might be 'experimental-lyr' from what I can see in the logs)
ie: "nslookup experimental-lyr"
Looking at the hostname itself - is that actually correct? I'm wondering if it is actually 'experimental-lyricue' but it is being cropped to 16 characters
It was being cropped because in lyricue_display I defined hostname as 16 characters
I've made a quick change to increase this to 32 and uploaded a new version (3.6.5) to launchpad a few seconds ago.
Hopefully launchpad will build the packages soon (I've marked them as 'high' urgency to see if that helps ;))
