If you're running Kile 2.1.0 there's another work around.
In Settings - Configure Kile - Latex - General, deselect "Automatically
insert opening and closing double quotes for LaTex
Then, further down the Configure list, go to Extensions. Select
AutoBrace and click on the settings block to the right, in the pop-up
window, deselect "Automatically add closing quotation marks"
Hope that works
