Acid pink colors in XFCE4 after dist-upgrade from trusty to utopic

[George Shuklin]

After upgrading trusty to final beta of utopic, all window decoration become extremely pink instead of sane colors (see attachment for example).

About half of the available themes is pink instead of normal mild blue colors (Numix, Mist, Industrial, etc) - all them are pink-decorated.
