--- Comment #5 from Nikolay Sivov bunglehead@gmail.com 2011-09-22 06:01:07 CDT --- Any particular reason to have native msxml3 for it? To properly fix something it's necessary to reduce number of external dependencies as much as possible.
Could you try to get a minimal list of needed overrides? To get icons working it sounds like gdiplus is a first candidate to start with.
Also please open a bug for msxml3 if it really makes difference at some point, and if not already opened of course.
