I might have stumbled onto something interesting.

I recently had a log-in that took significantly longer than usual, so I
decided to check my gdm logs to see if anything was suspicious. I found
this repeated many times over in the log:

The XKEYBOARD keymap compiler (xkbcomp) reports:
> Warning:          Compat map for group 2 redefined
>                   Using new definition
> Warning:          Compat map for group 3 redefined
>                   Using new definition
> Warning:          Compat map for group 4 redefined
>                   Using new definition
Errors from xkbcomp are not fatal to the X server

(Can someone smart shed some light on that?)

Now maybe I'm crazy, but the time it takes me to log in seems to be
related to the length of the log, i.e. the number of times that error
message was repeated in the log. After restarting my computer, my next
log-in went much faster, and checking the gdm logs shows that error
message far fewer times. Note :0.log.1 corresponds to the particularly
long log-in, the log is 6x bigger than usual, and the only difference I
noticed was the above error message is printed many many more times in
the bigger log.

Could this error be our culprit? I'd guess so, but maybe something else
causing the log-in to go slow and the slower log-in results in the error
being printed more?
