Yes, for me the working .eld has (modseq) while the current
nonworking one has (modseq . "99209").

For me, the difference is in the b here (and only the number is
different, not the structure), so I believe the active change may be
unrelated.


But I also see a difference in the first two elements after after the
string "commits":

working .newsrc.eld has
 ("commits" 3 ((1 . 96052)) …)

failing .newsrc.eld has
 ("commits" (3 . 1) ((1 . 96052)) …)

Note also that the backtrace said it failed at
 gnus-range-difference((nil . 95923) nil)
 nnimap-update-info(("commits" (3 . 8) ((1 . 95923)) …)
