It appears that the ColorPicker version check is failing on 30403.

If you replace:

if ColorPickerFrame.SetupColorPickerAndShow then -- 10.2.5 color picker overhaul

To:

if (select(4, GetBuildInfo())) > 100205 then -- 10.2.5 color picker overhaul

Then it works fine.

It appears 3.4.3 has the function its checking for but not GetColorAlpha.

This is line 58.

If you check by the Interface version instead and require it greater than the version that has it you will find it loads fine.

Maybe we need to use a direct version check that way or if its  3.4.3 and has the function we have another declaration?

Side note: Thinking on this I would say the fix should be something like the below as it started on that version so all after the below would be fine

if (select(4, GetBuildInfo())) > 100204 then

For the debug log I am getting:

Wrath does not have SetupColorPickerAndShow. You have an addon that adds it, and breaks the check.

It looks like its in this file: BagBrother/libs/Sushi-3.2-1/classes/checks/Color.lua

Which appears to be part of Bagnon.

Please complain to them and remind them that modifying global UI state is terrible.
