Sure, but I would expect DBus to be running a session bus already. I
would expect to see this:

martyn petunia:~$ ps -C dbus-daemon -o pid,uid,cmd
  PID   UID CMD
 5186   103 /usr/bin/dbus-daemon --system
 6232  1000 dbus-daemon --fork --print-address 20 --print-pid 22 --session

Well, we don't use PID files, we use DBus to manage if we are already
running or not. So if it comes back with that error, then it means there
is already a session running and the Tracker name is already in use.

Do they share the same /var? The only reason I ask, is that DBus has
files in there which could be causing the "already running" issue.
