... And immediately I realised that if I do this on the "All Mail" group, I will kill emacs, imap, and myself before getting to the list of mails. The main reason for why I wanted to display the labels in the first place was so that I would not have to re-label all mails whenever I was done with them and wanted to archive them away from the inbox. Hence, it makes (most) sense to use this in the INBOX group:

; ---
(defun gnus-user-format-function-g (headers)
  (concat
   (if (string= group "INBOX")
       (nnimap-fetch-gmail-labels number)
     (concat "-")
     )
   "")
)
; ---
