Description Michał D. (Emdek) 2013-04-17 14:05:18 UTC 
Due to some limitations of QColor constructors Plasma::ConfigLoader fails to load default value of QColor with alpha channel, both specified as: r,g,b,a or #AARRGGBB.
Since QColor seems to be not smart enough to correctly parse its input then it probably should be fixed (at least for 4.x lifetime) on Plasma level (KConfigXT itself may need the same fix / workaround), by checking if value fits pattern \d+,\d+,\d+,\d+ and split it and feed to another constructor. 
It may also check if value starts with '#' and has length of nine characters.

Reproducible: Always

Steps to Reproduce:
1. Set default value of entry of type Color to 0,0,0,50 or #10000000;
2. Load this value to KColorButton that has enabled alpha channel.
Actual Results:  
Button has invalid value (might be a bug in KColorButton too, which shows white on button but black in dialog)

Expected Results:  
Button should show correct value, with proper alpha channel value.
