I have given anons permission to block people (LocalSettings contains:
$wgGroupPermissions['*']['block'] = true;)

So as an anon, I tried blocking myself (by IP address) for 2 hours.

This worked. So then I logged in to my named account, with the intention of
unblocking my IP address.

What I would expect at Special:Ipblocklist is to see the blocked IP address in
the list. However, it says "The blocklist is empty".

Bypassing mediawiki and going to the db layer shows this is not the case:

mysql> select * from ipblocks;
+--------+-------------+----------+--------+------------+----------------+----------+---------------+--------------------+----------------+-----------------+---------------+
| ipb_id | ipb_address | ipb_user | ipb_by | ipb_reason | ipb_timestamp  |
ipb_auto | ipb_anon_only | ipb_create_account | ipb_expiry     | ipb_range_start
| ipb_range_end |
+--------+-------------+----------+--------+------------+----------------+----------+---------------+--------------------+----------------+-----------------+---------------+
|      1 | 192.168.0.2 |        0 |      0 |            | 20060714044007 |     
  0 |             0 |                  1 | 20060714064007 |                 |  
            |
+--------+-------------+----------+--------+------------+----------------+----------+---------------+--------------------+----------------+-----------------+---------------+
1 row in set (0.00 sec)

Then when I try to edit as an the anon, I get this message:
" Your user name or IP address has been blocked. The block was made by
[[User:|]]. The reason given is ' "

Is this normal? Doesn't a limited time block still appear in the blocklist? It
seems to work as expected provided the block is done by a named account, but
seems to get its knickers in a twist when the blocking is done by an anon.
