Update page breaks permalinks

Question

I am having a strange side effect since going to 3.3.1. When updating pages (or creating new ones) all of my permalinks break - clicking view page on the updated page in question will result in 404 not found. This does not happen with posts.

I was concerned it might be an issue with my new schema for permalinks /%postname%/ but I swapped it to YEAR/POSTNAME and did not see any difference. I checked and found a few duplicates in the post-name fields, I changed or deleted any questionable repeats. Still no change.

Here is my htaccess -

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

I've also looked at MonkeyMan's Rewrite analyzer and nothing seems amiss there.

Any advice would be appreciated. Let me know if there is other information you need.

I had tested it with all plugins off, and just as I was about to swap to 2011 I looked over all my custom taxonomies, which I coincidentally added around the 3.2.1 update. Lo and behold - I had foolishly added a 'year' taxonomy, changing that to 'show-year' seems to have licked it. Foolish mistake, thanks for the interest toscho. –
