In that case, it probably would have gone away had you simply logged out
and back in.

I wouldn't have bothered replying except for this:

Just for the benefit of anyone reading the mailing list archives: to call
that a similar error may be a bit of a stretch.  It's from 2003, it's on
a Windows NT machine, and it's for Amol Deshpande's precompiled zsh 3.0.5
which was already ancient at the time.

However, if you mean that when you wrote "instead of messages" above, you
were implying that the here-documents in zkbd were failing, I did find a
way to reproduce that:

schaefer<512> zsh -f
% umask 444
% cat <<\EOF
heredoc> Hi there
heredoc> EOF
zsh: permission denied
% 

Here-documents are implemented using temporary files, and when the umask
is such that the current user won't have permission to read the files
that he creates, here-documents will break.  Zsh is not alone in this,
although zsh's error message is more cryptic:

schaefer<513> bash    
[schaefer@torch tmp]$ umask 444
[schaefer@torch tmp]$ cat <<\EOF
> Hi there
> EOF
bash: cannot create temp file for here document: Permission denied
