after openexr was updated yesterday from 1.7.0-2 -> 1.7.1-1, digikam failed to start with the following error: digikam: error while loading shared libraries: libIlmImf.so.6: cannot open shared object file: No such file or directory /usr/lib/libIlmImf.so.6 used to be provided by openexr; now it's called libIlmImf.so.7 instead. providing a symlink with the old name, pointing to the new one solved the problem. bug: https://bugs.archlinux.org/task/31923 -- phani.
