User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; Avant Browser 

Description of problem:
On a fully patched RedHat 9 box the ftp client can segfault under the right 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Create an account on the FTP server with a non-existent home directory, eg: 
2. Use the FTP client to connect to FTP server, connect using new account
3. After the server responds with a '500 OOPS: chdir' error, repeatedly try ftp 
client commands until core dump.    

Actual Results:  [bpoyner@zippy bpoyner]$ uname -a
Linux zippy.ccac.edu 2.4.20-18.9 #1 Thu May 29 08:37:23 EDT 2003 i686 i686 i386

Expected Results:  No segfault.

Is this /usr/bin/ftp or /usr/kerberos/bin/ftp?
