404 on custom permalink pagination caused by bad htaccess

[nhumrich]

Seams this bug is lurking all over, but all have been marked as invalid, or problem not found.

When using custom permalinks, using the next button (aka page 2, 3, etc.) causes a 404 error.

Switching to default permalink structure fixed the problem.
The error still happens when default theme is used, and all plugins are turned off.

The error is due to the .htaccess file.
The htacess file looks like:

# 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 have changed the htaccess file to the following and it fixed the problem. (AKA, here is the recommended patch)

# BEGIN WordPress
<IfModule mod_rewrite.c>
ErrorDocument 404 /index.php?error=404
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

This sounds like a server configuration error outside of .htaccess, as a 404 handler should not be required to be invoked, as the Rewrite rule will match all URL's which do not exist on the filesystem.

It's more likely that the simple act of editing the .htaccess file was enough to trigger a cache clear on the server / to force apache to reload the file.
