Uwe, you could try out the current Git version instead of 11.88.  In
11.88 the :type of `TeX-view-program-list' changed from (alist ...) to
(repeat (list ...)).  Maybe Xemacs 21.4.22 has a problem with the alist
type, who knows...

Another blind guess is that the value is already customized and doesn't
match the type anymore, and thus you get an error when the widgets are
created and tried to be filled with the current value.  So delete the
customization, restart, and try again.  Maybe that helps...

Bye,
Tassilo
