Still an issue in 14.04, but the workaround I use is to set the color in the Trolltech.conf (home/.config/Trolltech.conf) instead of with the qtconfig tool. At the end of the file, palette colors are defined. I edited the last two colors of each palette (active/inactive/disabled) and was able to change my tooltip background and foreground colors to match my theme.
