Comment (by jeichorn):

 So this finally happened to me again.  I was able to trace down the cause.

 Objects are being stored in the uninstall_plugins due to the uninstall
 being callbacks being on classes.  The un-serization happens in the first
 plugin that calls register_uninstall_hook, but the classes used by other
 plugins aren't loaded yet, set they un-serialize as
 __PHP_Incomplete_Class.  Then when the next plugin calls
 register_uninstall_hook, its serializing an object with the actual class
 name so its a different value in PHP, so the comparison in update_option
 fails.
