gnus-registry- functions seem not to work in Xemacs (21.4x Mule)

[Uwe Brauer]

Hello

I downloaded the recent cvs version of gnus and put the relevant setting
in my .gnus file, namely 

(setq gnus-registry-max-entries 2500
       gnus-registry-use-long-group-names t)

(gnus-registry-initialize)

I tried then to set gnus-registry-set-article-Important-mark
in a nnimap folder but nothing happened.

My setting is 
for  gnus-summary-line-format
"%U%R%z%I%N %(%[ %-20,20n%]%) %-23,23~(form (rfc2047-decode-string (gnus-extra-header 'To)))@  %D %k %L   %s
"
should this be changed.

If somebody, using xemacs, uses the registry function successfully I
would appreciate his/her help.

thanks

Uwe Brauer
