I was able to work around this by using <TAB> to select a source and <SPACEBAR> to activate the check box. Now I can check/uncheck at will and have no errors.
I noticed yesterday when I encountered the bug it didn't prompt me for password when I made a selection, but today it does (whether I check or uncheck the box) every time I open that dialog.
Hope this information helps. If I figure out more details I'll post them as well.
