It looks like that nobody is actually issuing the indicator-services-end upstart signal, so the stop events of *all* indicators for lightdm sessions never get fired. The other indicators just die because the session bus disappears under their feet, but indicator-sound-service keeps hanging around (even respawning pulseaudio in some cases!).
I don't really know who's at fault here - IMHO not upstart, which is doing the right thing (respawning dead indicators until they try to respawn too fast). Perhaps the greeter should clean after itself - after all, the indicator-services-start is fired by it. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1322275 Title: lightdm sessions started by dm-tool lock (or a session locker) never get closed Status in Light Display Manager: New Status in lightdm package in Ubuntu: Confirmed Status in upstart package in Ubuntu: Confirmed Bug description: dm-tool lock starts a new lightdm greeter (for unlocking) and a new logind session.
