Version 4.0.1 of Kasablanca has been released. I didn't need to modify the ebuild anything apart from renaming it and creating the new digest. This version, among other things, fixes an evil bug in the 4.0 version which may cause it to delete (a lot) more files than expected when trying to remove directories. I suggest that you somehow restrict access to the 4.0 version. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Done by voxus. Thanks you both.
