Can't set Custom color

Original Reporter info from Mantis: Valdas

Reporter name: Valdas Jankūnas

Description:

I can't set custom color in "IDE Options -> Editor -> Colors": every time I set value in Custom Color dialog and close it, color automatically changes to different value.

Steps to reproduce:

 - open "Tools -> Options... -> Editor -> Colors",
 - change Foreground Color of object (f.e. "Comment") to Custom,
 - in opened dialog set value of color (f.e. to blue),
 - close color chooser dialog - in code preview pane color of that element is wrong (black), but if You open Custom color dialog again then You see correct value,
 - close options dialog - color of adjusted element in source editor becomes wrong,
 - again open options dialog and custom color dialog of previous changed element - color value now changes to that wrong color.

Additional information:

Tested in Qt and in Gtk2.
In Gtk2 ws Color dropdownbox is weird (see "strange_box.png", mouse ower 4 element from top).
