Maybe we should move all this logic out of the ctor and into an Init method. 
Ctors should never fail and looks like there is opportunity to fail in all this
logic.

[jianli, 2011/05/24 18:20:24]

Move this logic to AboutPanelBubble::Show and make it return NULL if the
extension cannot be found.

why *3 ?  I was expecting *2.

Indeed one kBubblePadding is for the spacing between the icon and the remaing
contents. Used a new constant for this.
