Lars,

finally, yes!  I have had debug-on-error turned on and have been trying
Js periodically the past day or two and finally I got an error with
corresponding backtrace:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (args-out-of-range 13294 19274)
  gnus-agent-fetch-articles("nnimap+ucl:lists.org" (2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 ...))
  gnus-agent-fetch-group-1("nnimap+ucl:lists.org" (nnimap "ucl" (nnimap-address "imap-server.ucl.ac.uk") (nnimap-inbox "INBOX") (nnimap-stream ssl)))
  gnus-agent-fetch-session()
  call-interactively(gnus-agent-fetch-session nil nil)
--8<---------------cut here---------------end--------------->8---

However, I don't think it's particularly helpful.

I think I've narrowed down the conditions under which this happens: if I
read a group and exit it, with articles being expired as a result, and
then ask the agent to fetch articles without saving first, this seems to
happen.  If I save ('s' in Group buffer), this doesn't seem to happen or
if no articles have been expired since the last save it doesn't seem to
happen either.

But that's just conjecture... I have not been scientific in my
experimentation (yet)!

All of this with gnus from git from yesterday late (GMT).

Anyway, I hope some of this helps.

Thanks,
eric
