bug#24966: 26.0.50;

[Mark Oteiza]

Hi,

dd98ee8992c3246861e44 appears to be the culprit for breaking the
following from -Q:

1. C-x C-f /tmp/foo.tex
2. M-x reftex-mode
3. Insert the following: \label{foobar}
4. M-x reftex-goto-label

and, when attempting to complete, a wrong-type-argument error occurs.
