Please describe the problem:
I simply cannot associate a group with a certain color in Evolution 2.10.2. When I change the color of a group and then press the OK button in the "Category properties" window, it reverts to the default black color.

I have the following Evolution packages installed:
evolution 2.10.2
evolution-webcal 2.10.0
evolution-data-server 1.10.2

Steps to reproduce:
1. Install Evolution.
2. Start Evolution.
3. Go the the contacts.
4. Create a contact.
5. Choose categories.
6. Create a category.
7. Try to set a color.
8. Press OK.
9. View the properties for the group.


Actual results:
The group color is black, and always black, no matter what I do.

Expected results:
I'd expect it to keep the color I choose myself for the group.

Does this happen every time?
Yes.
