Description:
I could reproduce this on my local server MacOSX 10.4.11/apache/MySQL MediaWiki1.12.0 and a bit old Renameuser extension
and also, on ja.wiktionary.org twice.
It can reproduce as blow.

1. making a new account "foo"
2. (sysop) block "foo"
3. (b_crat/sweard) rename user "foo" to "bar"
4. see ipblockliset, it shows like "blocked user:foo at xxxx-xx-xx" and somr other info
5. someone get accout foo again
6. foo *DO* not blocked, although he's on the ipblocklist.

I assume SUL may makes many of user rename job for b_crats on every project,
I think it is not critical software probrem in real means, but it IS psychological critical problem for wikimedia project
with SUL as I think.

to avoid this, sysops on every project need to unblock the one who has been blocked and need to rename
before or after renameuser.

thanks
