This package currently uses rsvg-convert to make PNGs out of the upstream SVGs, but I think it can use ksvgtopng from kde-plasma/kde-cli-tools instead. The tango-icons configure.ac says, SVGCONVERT="" AC_MSG_CHECKING([SVG to PNG conversion method]) if test "x$enable_large_bitmaps" = "xyes"; then PKG_CHECK_EXISTS([librsvg-2.0 >= 2.12.3], [enable_large_bitmaps=yes], [enable_large_bitmaps=no]) if test "x$enable_large_bitmaps" = "xyes"; then svgconvert_prog="rsvg" else svgconvert_prog="ksvgtopng" fi ... I haven't actually tried it (installing KDE wants to make a mess here), but it would be nice to have the alternative for people who already have the KDE (but not gnome) stuff installed.
Same would be needed for tango-icon-themes-extra. Tried it but.. ``` Aborted (core dumped) qt.qpa.xcb: could not connect to display qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.

(I'll CC kde@ in case they know of some way to work around that)
Probably needs virtualx to work?
