when i launch dolphin with KRun::runUrl("trash:/", "inode/directory", 0);
i get a Malformed url: "trash:/" error message
i think it's a dolphin issue because if i put konqueror as the default app for the inode/directory mimetype it works correctly.
how to reproduce it:
make sure dolphin is the default for inode/directory and try to open the trash with the trashcan plasmoid or simply drag the trash from dolphin sidebar to plasma desktop, clicking on it will get the error
