Buggy Events Filtering?

[Darius1968]

In this log file, can be found my focus having been set on "This Week", in the Collections view.  My Global Filter had just the Events filter ticked, and it faithfully shows that for the scope of files active (45), there are two events, for which I had ticked one of those.  The filter is showing that I have no files, however.  And, if I click the invert filter button (in the Events Panel) it shows all 45 files!
