Can't Delete A user Chain

Hi,

Seemed that I have came across a bug for ebtables, below is the script that I have writen to reproduce the error

### Start Script ###
#!/bin/sh

/sbin/ebtables --init-table
/sbin/ebtables -N 1
/sbin/ebtables -N 2

/sbin/ebtables -A INPUT -s 00:00:00:00:00:02 -j 2
/sbin/ebtables -X 1
### End Script ###

If the "-A INPUT" line is commented, it worked fine. Saw the following in syslog:

#### Start Syslog ####
kernel: kernel msg: ebtables bug: please report to author: bad destination
#### End Syslog ####

Seemed to me that I can't delete chain if there is a reference to a chain defined after the chain. ( confusing, I know, I think the example above is easier to understand! ).

Any clues? Is this a bug or did I missed something?

Some Info on my machine: 
KERNEL = 2.4.20 (clean from ftp.kernel.org)
KERNEL PATCH = ebtables-v2.0.003_vs_2.4.20.diff
EBTABLES = ebtables-v2.0.2.tar.gz

Cheers,
