[Sugar-devel] Sugar in Fedora 14

[Bert Freudenberg]

Running as a session it does not ask for a keyring password. Good. But there are no peers in the neighborhood view either. There are no network logfiles created in .sugar/default/logs, though according to ps, telepathy is running. Presence-service fails with the same error.

This avoids using presence-service at startup. Sharing will still not work with the borked PS of course.
