An excellent question. I see the same behavior on a fairly stock Fedora
17 host too. I can only assume that the actual desktop session is
ending up with a different keyring session than gdm had.

For the sake of curiosity, when logging in remotely with x2go (based on NX), the session keyring is okay:
$ keyctl show
Session Keyring
420490248 --alswrv   1000   100  keyring: _ses
318990990 --alswrv   1000    -1   \_ keyring: _uid.1000
909936426 --alswrv   1000   100   |   \_ user: 75fbf6399a9cf084
909201030 --alswrv   1000   100   |   \_ user: aa10afc0620e9893
256104206 ----sw-v   1000   100   \_ logon: cifs:a:192.168.1.3

(That is for another user, the extra keys are for ecryptfs).

Later on I will try to run startx from console as well to see if GDM is the suspect.
