Flot interface can't find events when using mysql backend

[mattpascoe]

While using a version of trunk pulled on 9/19/12 I have found that when I use the MYSQL database option I am unable to render events in the flot interface. Direct render urls and the normal web interface are all able to find and generate event data on the graphs.

When in flot if I proved '*' as the search in the event field it shows a red bar as if it is unable to find the events. It also fails when searching using a tag name. I can see the events listed in the /event/ interface as expected.
