desktop.el doesn't save TAGS files (skipped according to the current
default value of the option `desktop-buffers-not-to-save'), but saves
information about TAGS-LISP. This causes `find-tag' (M-.) to fail after
restoring the desktop due to the attempt to call nil function:
Debugger entered--Lisp error: (void-function nil)
nil()
tags-included-tables()
tags-table-extend-computed-list()
...
That's because when desktop.el restores TAGS-LISP, it doesn't
initialize its local variables by the function `initialize-new-tags-table',
so `tags-included-tables-function' has the value nil, and
`tags-included-tables' fails when it tries to call it.
I think desktop.el should not save TAGS-LISP and other similar files too:
