Answer 1

As a workaround I have converted the icons from svg to png, then placing them in share/icons. The icons now show up, though there is a minor problem: when the search entry is empty, an additional magnifying glass icon will shop up on the right.

The additional magnifying glass will be replaced by the "clear" icon when there is text in the entry, so I do not consider this that much of a problem... (Although admittedly it looks quite weird...)

As this is only a workaround and not a perfect solution, I will not mark this as accepted answer. I think the problem may be related to how the svg files are displayed, but I have all the DLLs from here so I don't really understand what the problem is.
