Git commit d82e4917f7286984bce16c2fa36ea4e9f6a24453 by David Faure.
Committed on 17/02/2013 at 21:54.
Pushed by dfaure into branch 'KDE/4.10'.

Fix crash due to dangling session pointer in m_pendingInitialSession.

This happens after disconnect() kills all sessions (e.g. due to losing
internet connection while the password dialog is up, or explicit toggling
of offline/online status, or due to the "SSL not supported").
