 When I try to open this URL …

 http://wordpress.org/support/topic/hasn’t-this-become-obsolete



 {{{

 … I get in Opera 12 a useless response, sending me to the same address
 with non-ASCII characters encoded in lowercase:


 {{{

 obsolete?replies=1

 }}}

 This continues until my browser has enough.

 In Chrome, I don’t get a 302, the correct page is sent instead.

 Looks like broken UA sniffing.
