How do I prevent Skype from automatically starting every time I boot my Xubuntu 12.10 netbook?

Things I've tried:

• Removing it from the Settings Manager->Session and Startup->Application Autostart - couldn't find it in the list.


• Checking for a relevant setting in Skype itself - couldn't find anything of the sort.


• Using BUM to turn it off - again, couldn't find it in the list.


• Uninstalling Skype with apt-get remove skype --purge and hoping that it removes all the settings as well - it didn't.

Save for reinstalling, what else can I try?

While on the same note - how is it possible for Skype to autostart without going through the normal Upstart route?

EDIT: Couple of more things I tried:

• Looking for anything similar in Skype support - I didn't expect to find anything, and I didn't.


• Looking through the .Skype folder in my home directory. I did find a couple of files which looked promising (.Skype/shared.xml, .Skype/[my username]/config.xml, .Skype/[girlfriend's username]/config.xml), but looking through them didn't yield anything. Plenty of SQLite files though. Could it be that this setting is somewhere within?
