Yes, this is indeed a bug. Probably more like these will show up (due to old code), but this one got fixed *good* in the trunk version ๐
If you’re interested in testing the trunk version? It already has evolved a lot (again):
* Bugfix: stripslashes needed for custom attributes
* Bugfix: when using scope=today, the sql query was wrong and thus ignored other conditions
* Bugfix: characters now get escaped ok in locations as well
* Feature: you can now choose whether or not registrations need approvements, and then manage pending registrations
* Feature: you can now edit the number of seats somebody registered for, in case they change their minds
