No, QSessionManager is not for crash recovery. It's a mechanism for
so-called "session managers" to restore your desktop when you log back
in. For example, if you logged out with firefox running with 4 tabs,
the session manager would tell firefox to save it's state. When you
log back in, the session manager will launch firefox automatically and
ask it restore itself from it's previously saved state. In
http://en.wikipedia.org/wiki/Session_management, QSessionManager
relates to "desktop session management"

For crash recovery, you need "browser session management" (in the
wikipedia link). This involves your app periodically checkpointing
it's state using QSettings or such.
