 Replying to [comment:23 RJVB]:
 > @jjstickel: could you please try with the new kapplication raster patch
 I pasted (inline) into the PR (https://github.com/macports/macports-
 ports/pull/3022#issuecomment-441384590)?

 I replaced the `patch-kapplications-raster.diff` with that one and rebuilt
 (and installed) kdelibs4. What functionality do you want me to try?
