(wrong-type-argument number-or-marker-p nil) in gnus-range-difference

[Kevin Brubeck Unhammer]

I've been getting these errors like

once in a while, on opening Gnus. I typically "solve" them by removing a
line from ~/.newsrc and trying again. The actual error happens in
(> min1 max1) in gnus-range-difference; the previous line is nnimap.el:1481

                   (read (gnus-range-difference
                          (cons start-article high) unread)))

Does anyone know of a better fix to this than randomly editing newsrc's
until it works?
