Huh. I wonder why the second one isn't getting hung up on
`gnus-list-of-unread-articles'. Anyway, in both cases it seems like the
problem is that Gnus thinks there is a truly enormous number of messages
in your inbox (537,842,298 of them!), and is trying to handle that
quantity. I'm assuming you don't actually have half a billion messages?
How many *do* you have? I can't imagine how Gnus got that confused, but
you might try doing "C-u M-g" on your inbox in the *Group* buffer and
see if that corrects the problem.
