Did you change the style for Disabled icons in the KDE advanced icon settings? 
The last person to report this bug had changed them so they appeared the same
as Enabled icons.

So what is the standard setting for disabled icons?

I haven't changed this setting, and currently there is no effect set for disabled icons...

But if this is the "bug", why does Gadu schow offline and online icons as it is supposed to do?

To configure the disabled icon, go in kcontrol, icons, experimented, all icons,
disabled, define effect.

(--- now this is a message for the kopete theam ---)

Anyway, i personally think we should not use the "disabled icons" for offline,
but always use grayed icon.

1) i don't see how offline = disabled
2) if you use the transparency effect, that broke the drag and drop icon of
offline contact
3) if you select an effect which is not different enough than normal you don't
see the difference.

I think that always gray the icon is probably the best solution.
Anyway, the problem is that one can't see the diference between two different
account colors.
But i found no effect that render nicely which let see the account color, and
which is different enough from online.
anyway, 95% gray is probably a solution.
Or maybe using a different overlay icon for offline (like gadu)

Ok, setting the effect to grayed icons did the trick for me, but I agree with
Olivier, not to use this standarized disabled effect...
For reasons mentioned above.

cheers

Agreed - I don't like it any more either.

CVS commit by ogoffart: 

Change the effect of the offline icons.
Don't use anymore the disabled effect since it have nothing to do with offline.
I used a 85% gray, so we still can see the account color.
