Alpha value is not applied when color is set to 0 0 0 (black)

[Kai Hendrik Behrends]

I'm trying to write a screenlet and the first thing I'm doing is adding a rectangle and coloring it.
See the code here: http://paste.ubuntu.com/614223/
When i set the color to 0 0 0 (black) and add an alpha e.g. 0.5 the alpha doesn't get applied other colors than black work just fine.
(another thing why doesn't the font i set get applied too?)

Setting of the font does not work because you don't set only family of the font, but also size and weight. This is not supported like that because of pango.FontDescription set_family does not support it. I filed a separate bug report for that, see https://bugs.launchpad.net/screenlets/+bug/789775.

This bug seems to be quite hard to track. I think you can avoid the problem just now by describing the default color as 0.01 0.01 0.01 (almost black).

Yes that's they way I'm avoiding the behavior right now.
This also affects the Clear Calendar and the Clear RSS Screenlets i believe.
