Description (last modified by ryan)

[8100] changed the behavior of maybe_serialize(). Instead of serializing an already serialized string, the string was returned as is. This broke plugins that passed serialized data to update_option()/get_option() expecting it to come back serialized. Instead it came back unserialized.

This has to be one of the dumbest things I've come across in a while. Why would it ever be a good idea to serialize an already serialized string? I came across this trying to figure out why custom fields with serialized strings stored in them were showing up doubly serialized.

Specifically, I'd export a page, then import it using the built-in Wordpress UI and the plugin using the custom field no longer worked as intended because the value was doubly serialized. Ticket #4028 seems to indicate this very bug was fixed 2 years ago, only to be re-introduced a year later.
