Do you have a message number "1" (or something else low in that folder)?

If so ... yeah, okay, that's going to happen (at least it doesn't crash).
The folder structure has some fields which are allocated based on the number
of possible entries, which start from the lowest numbered message and range
to the highest numbered message.  All of those commands don't have hardwired
limits anymore, they allocate as much memory as they need ... until they
can't anymore, as you've discovered.  I'm not sure there's a great solution
to that; redoing the folder structure to handle a sparse folder layout is
more work than I personally want to do right now.  Also, we probably have
some overflow problems when you get message numbers that high.
