Integer constant overflow in reader

[David Lim]

I've been using gnus to read mail for quite a while now. But suddenly,
when I try to read my INBOX (using nnimap). I get the following error (I
set debug-on-error to get the stack trace):

Signaling: (invalid-read-syntax "Integer constant overflow in reader"

How do I clear it? I get it everytime I try to access my INBOX now.
