This was an accidental discovery I was shipping the updated nfs-utils around to various systems and on one I had a symlink nfs1 --> /nfs1 under a user account. put nfs* immediately core dumps with a segmentation fault. put nfs-* works, also oddly enough mput nfs* works to where it wants to also upload the symlink/directory. Like I side I dont knowhow much of a bug this is but I thought I report it anyway.

The symlink seems to be a red herring. I can trigger this also with 'put *' and regular files. Poke around with gdb and you see that the seg fault is in a free, relatively obvious conclusion to come to. Comparison to the netkit ftp source (which has the same ancient base as the mit code) shows that the free in cmds.c:1863 (krb5-1.2.1) isn't present in the netkit source. Removal of this line seems to fix the problem for me
This should be fixed in krb5-1.1.1-25 and krb5-1.2.1-9. Until Raw Hide gets refreshed, you can grab updated packages from http://people.redhat.com/krb5/.
