when you install kde-base/gwenview, but don't have any kde4 packages in your system, dependencies it pulls make it unable to delete images to the trash (message about unknown trash:/// protocol pops up) after installing kdebase-meta , deleting images in gwenview works fine. my guess is that kdebase-kioslaves are not installed. Reproducible: Always Steps to Reproduce: 1. start with a system that does not even have kdelibs 4.x installed (no kde4 packages) 2. install media-gfx/gwenview, which should pull necessary kde4 packages as well. 3. run gwenview and try moveing some files to the trash (normally, via pressing DEL) 4. install kdebase-meta 5. now deleting files works Actual Results: gwenview cannot delete images. Expected Results: gwenview should be able to delete images. kdebase-meta installed with USE="-symantic-desktop" - that might affect dependencies.
I'm almost sure this is another case of optional run-time deps. @kde: Did we / can we get to a decision about optional run-time deps?
