ebtables -X does not delete all unused chains

Needless to say I am playing with ebtables and I am finding a few bugs.  
I don't know if the developers will be happy or if they will get tired 
of all my bug reports. :-)  I'm not trying to make the developer's life 
difficult.  I promise.

I am running 2.0.8-rc2 + segfault patch.  I am writing a script to 
program my bridge rules.  At the beginning of the script I have the 
following commands:

    ebtables -F
    ebtables -X

In theory, ebtables should flush all the chains in the default table and 
remove all unused user-defined chains.  I found the -X command, 
however, is not deleting all the user-defined chains.  It only deletes 
the odd-numbered ones (as given in the list) and the even ones remain 
intact.  Here is the example, starting from scratch:

-------------------------------------------------
[root@slim-dev ~]# ebtables -N FIRST
[root@slim-dev ~]# ebtables -N SECOND
[root@slim-dev ~]# ebtables -N THIRD
[root@slim-dev ~]# ebtables -N FORTH
[root@slim-dev ~]# ebtables -N FIFTH
[root@slim-dev ~]# ebtables -L
Bridge table: filter

[root@slim-dev ~]# ebtables -L

[root@slim-dev ~]# ebtables -X
[root@slim-dev ~]# ebtables -L

Bridge chain: INPUT, entries: 0, policy: ACCEPT

Bridge chain: FORWARD, entries: 0, policy: ACCEPT

Bridge chain: OUTPUT, entries: 0, policy: ACCEPT

Bridge chain: FORTH, entries: 0, policy: ACCEPT
[root@slim-dev ~]# ebtables -X
[root@slim-dev ~]# ebtables -L
Bridge table: filter

Bridge chain: INPUT, entries: 0, policy: ACCEPT

Bridge chain: FORWARD, entries: 0, policy: ACCEPT

Bridge chain: OUTPUT, entries: 0, policy: ACCEPT
[root@slim-dev ~]#
-------------------------------------------------

This bug is not critical, since ebtables is still useable and I can work 
around the bug.

Thanks again for your help.
