         This is used for a type that appears as an alternative inside of
         `choice';

and:

     If `nil' is not a valid value for the alternative, then it is
     essential to specify a valid default with `:value'.

(Of course, this remark does not apply to const.)  Sometimes you can
get away with not doing that.  You can get away with it for the
function part of your choice, because there 'ignore is used as default
if you do not provide any.  Apparently not for your list choice.  What
about the following?  (Seems to work for me)

(defcustom my-test 'foo-bar
  "Foo bar"
  :group 'LaTeX-macro
  :type '(choice (const :tag "TeX search" foo-bar)
                 (function :tag "Other function")
                 (list :value ("Antibes" "Warsaw")
                       (set :inline t
                            (const "Antibes")
                            (const "Warsaw"))
                       (repeat :inline t
                               :tag "Other"
                               (string)))))
(customize-variable 'my-test)
