Comment 73 for bug 128803

I think i might have the reason for the problem here; I noticed in my .xsession-errors file had a number of errors in it, this for example:

(process:5921): Gtk-WARNING **: This process is currently running setuid or setgid.
This is not a supported use of GTK+. You must create a helper
program instead.

Was when I was logging in, and this was coursing the slow down, I also noticed this:

** (x-session-manager:5918): WARNING **: Couldn't connect to PowerManager Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

When I try and logout, the last message does mention network connections, but I don't know how they're linked, as my loopback is fine (following previous posts, I checked it was up before logging on) and all but my wireless in disabled, any ideas? .xsession-errors log attached
