The correct syntax would be:
(operating-system
;; …
(services (remove (lambda (service)
(or (eq? (service-kind service)
wicd-service-type)
(eq? (service-kind service)
avahi-service-type)))
%desktop-services)))
As David notes, ‘%desktop-services’ is a list of service objects. To
remove elements from a list, the right procedure is ‘remove’ (info
"(guile) SRFI-1 Filtering and Partitioning").

I’ve added this example in commit 5d94ac5.
HTH!
