Editclear icon bug

[Jürgen Spitzmüller]

With qt5/svg icons, go to preferences and type something in the search bar
of the dialog. A huge "editclear" icon appears. Apparently the pixmap size
of the svg icon is wrong.

The attached patch solves it, but I am unsure if it is the best fix.

Stephan, Enrico?
