It appears that for some reason, during the configuration for rhythmbox- ubuntuone-music-store, something segfaulted (probably gconftool). Unless there is a crash log for that somewhere, it is doubtful we will be able to do anything. It looks like apt decided to run dpkg --configure -a automatically though, which may have resolved the failure on your machine.
