Agent off at restart

[Nicolas KOWALSKI]

Hello,

I just upgraded my Gnus to v5.13, using the emacs23 debian lenny
backport.

Since then, I noticed that each time I restart Gnus, my nnimap server is
not agentized anymore. Here is what I see in the Server buffer:

     {nnfolder:archive} (closed)
     {nntp:} (opened)
     {nnimap:} (opened)

I have to re-add agent (J a), but at next start, it is lost again.

My gnus-agent's value is t.

My gnus-secondary-select-methods's value is
((nnimap ""
         (nnimap-address "localhost"))
 (nntp ""
       (nntp-address "localhost")))


Any idea ?

Thanks,
