The theme engine error handler debug output isn't used for Exceptions in the code that pulls colors from XML.

This needs to be used there, but not right now as it's late at night.

Basically this part where the Exception is caught:

#Region "Button BackColor"
        ' Only pull the Button BackColor element from XML if it exists.
        If themeSheet.SelectSingleNode("/UXL_Launcher_Theme/Theme_Colors/Button/BackColor[1]", themeNamespaceManager) IsNot Nothing Then
            Try
                colorButtonBackColor = ColorTranslator.FromHtml(themeSheet.SelectSingleNode("/UXL_Launcher_Theme/Theme_Colors/Button/BackColor[1]", themeNamespaceManager).InnerText)
                debugmodeStuff.updateDebugLabels()
                ' If the element isn't a valid HTML color, just replace it with the default.
            Catch ex As Exception
                colorButtonBackColor = Color.Transparent
            End Try
        Else
            ' If the element doesn't exist, overwrite it with the Default theme's value.
            colorButtonBackColor = Color.Transparent
        End If
#End Region

Actually, is this really that important to have it go into the debug output?

Guess this isn't going on the changelog.
