That call (XScreenSaverQueryInfo) will tell you whether the screen is
currently being displayed and how long until it will go to the saver (if
displayed) or how long it's been in screen-saver mode (if not displayed).

My guess would be that they're using this information to determine
whether or not to scan for new email.  Why bother pulling data via POP
or IMAP if the screen isn't being displayed at all?  Especially since
most users leave their email client up all the time.

That's probably the right question.  But I don't see a reason for a core
dump here.  Are you sure that's the thread that faulted?
