Squatter crash with statusdb

[Andy Fiddaman]

Hi,

I've just upgraded my Cyrus installation to 2.4.17 and squatter is
crashing in statuscache_buildkey() because userid is NULL.

I'm not sure what the best fix for this is. Should squatter even be using
the statuscache or should it populate "cyrus" as the username when
initialising the index, or something else?

Thanks,

Andy
