No, that just means gdm crashed.

Look at the surround debug spew:

Oct 20 09:54:30 ubu-desktop gdm[4624]: DEBUG: Attempting to parse key
string: daemon/FirstVT=7
Oct 20 09:54:30 ubu-desktop gdm[4624]: GLib-CRITICAL:

It's blowing an assertion when attempting to parse the daemon/FirstVT
key (the message makes it sound like a GError isn't getting properly
initialized to NULL), then it crashes trying to parse
security/DisallowTCP.
