Let's see...

The `gnus-cache-open' function is called at startup, so long as
`gnus-use-cache is non-nil.

When `gnus-cache-open' is called, it will call `gnus-cache-read-active',
which will always create the hash table in question, one way or the
other. The only way it will not call `gnus-cache-read-active' is if this
test fails to pass:

(or (file-exists-p gnus-cache-directory)
    (and gnus-use-cache
	 (not (eq gnus-use-cache 'passive))))

I'm guessing your `gnus-cache-directory' points to a non-existent
directory? I'm also assuming your `gnus-use-cache' is 'passive.

It's a bit weird, though -- if the directory doesn't exist but
`gnus-use-cache' is non-nil, it seems like Gnus should either create the
directory, or just not attempt to use the cache.

As it is, `gnus-cache-read-active' creates the cache directory, but only
if... it already exists.
