Occasionally "rotate left" or "rotate right" works, but almost always Digikam crashes.
You should definitely change to version 5 in general. Philip maintains a Ubuntu PPA https://launchpad.net/~philip5/+archive/ubuntu/extra/ or you always find the most recent version at https://www.digikam.org/download To check this specific issue, please try to reproduce the issue with the pre-release Appimage from https://drive.google.com/drive/folders/0BzeiVr-byqt5Y0tIRWVWelRJenM Just download the file, make it executable and execute it.
