with poppler-0.58.0 a new object API has been introduced requiring bigger changes to poppler consumers.
As ususal no talking here please. If you found a package not building against =poppler-0.58.0 please file a new bug and make it block this bug.
Please add media-gfx/inkscape-0.92.1-r1 #630482
It seems we are done here, stabilisation for fix of the last remaining dependency is ongoing.
