[EMACS] bug in version control with Emacs 21.1 and 21.2

[Laurent MUGNIER]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.1.1 (sparc-sun-solaris2.7, X toolkit, Xaw3d scroll bars)
 of 2003-03-03 on yeti
configured using `configure  --prefix=/usr/gnu'
Important settings:
  value of $LC_ALL: nil
  value of $LC_COLLATE: nil
  value of $LC_CTYPE: iso_8859_1
  value of $LC_MESSAGES: nil
  value of $LC_MONETARY: nil
  value of $LC_NUMERIC: nil
  value of $LC_TIME: nil
  value of $LANG: C
  locale-coding-system: iso-latin-1
  default-enable-multibyte-characters: t

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

In my .emacs I setq
      vc-checkout-switches "-zLT"       ;default Time Zone = Local (RCS/CVS) 
      vc-checkin-switches "-zLT"        ;idem
      vc-register-switches "-zLT"       ;idem

If I then try to register a file, I get the following error message:
apply: Wrong type argument: stringp, ("-zLT")

I guess that the "-zLT" string is converted to a list and then checked as a
string! 

If the string is "zLT" instead I get the same error.

This bug was not present in Emacs 20.6 and 20.7.

If I remove the 3 customization lines above from my .emacs, the registering
works fine.

Thanks in advance for your help.
