cvmfs-server 2.2.1 cvmfs_swissknive hash is broken

[root@idris ~]# echo 1234 | cvmfs_swissknife hash -a -f
Aborted

[root@idris ~]# cvmfs_server resign
Signing 30 day whitelist with master key... /usr/bin/cvmfs_server: line 157: 12382 Aborted $(__swissknife_cmd) $@

The error message is really:
9783 sendto(3, "<11>May 5 01:13:40 cvmfs_swissknife: tried to generate hash context for unspecified hash. Aborting...", 102, MSG_NOSIGNAL, NULL, 0 <unfinished ...>

Tried building it from source, and it then only segfaults when trying to use hash.

My stratum 0 is pretty much broken now, can this issue be looked into quickly?
