Comment:

 I am having the same issue and so far all my tracking and debugging points
 to WP.

 1. .htaccess and mod_rewrite are working fine - verified by the fact that
 individual posts are working and also by examining Apache's mod_rewrite
 log file.
 2. confirmed it is not a plugin issue - turned off all plugins, issue
 still exists.
 3. confirmed it is not a theme issue - issue still exists with default
 TwentyEleven theme.

 Any permalink structure which has the variables %category% or %tag% does
 not seem to work.
 I am using /%year%/%monthnum%/%postname%/ as my permalink structure. With
 that, individual posts work file. Accessing any category or tag archive
 /%category%/<name> or /%tag%/<name> results in 404 Error.

 However, if I change the permalink structure to
 /%category%/%year%/%monthnum%/%postname%/, all of sudden, even individual
 posts start returning 404 errors.
