I have the following preliminary patch to fix A T with the agent (and
the nntp backend).  Could you try if it fixes your problem, too ?

Subject: [PATCH] When the agent is active gnus-summary-refer-thread inserts
 only headers which are already in the agent cache but it
 doesn't try to fetch old headers.

Check this fix: Using uncached-articles or (car articles) might not be
quite right (but then again, it might).
