This seems like two bugs:
1) Unity plugin mysteriously disabled, have to re-enable via ccsm
2) Launcher icon size can't be adjusted
I just experienced #1. The only thing I changed on the system between working and broken login sessions was to install gparted (0.16.1-1), which also installed libgtkmm-2.4-1c2a (>= 1:2.24.0)
I also found this in the syslog:
Feb 7 12:32:05 Arcturus gnome-session[1803]: WARNING: Child process 2057 was already dead.
Feb 7 12:32:05 Arcturus gnome-session[1803]: WARNING: Application 'compiz.desktop' killed by signal 9
Feb 7 12:32:05 Arcturus gnome-session[1803]: WARNING: App 'compiz.desktop' respawning too quickly
Feb 7 12:32:05 Arcturus gnome-session[1803]: CRITICAL: We failed, but the fail whale is dead. Sorry....
Kind of trouble-shooting in the dark here, but that's the best I've got. Beyond that I don't know what could have caused it.
