This bug affects the publisher + gateway configuration.
Given a repository:
It is permitted to acquire a lease on a subdirectory that will be created during the transaction.
$ cvmfs_server transaction test.repo.org/NEW_DIR
The following command will cause the publication to fail:
$ cvmfs_server transaction test.repo.org/DIR/SUBDIR
The crash is due to the fact that both DIR and SUBDIR need to be created.
Should this case be supported?
