Description
I have traced this error. The cache entry of some menu items keep getting corrupted: the "options" value is already unserialized as an array in the cache entry, when it should be stored as a string (as for other menus item).
This happen for one of the Primary Links menu items, and I can reproduce the same error by creating another menu item linking to the same node. No idea why, but I suspect it may be due to some node access control (which is pretty messy in this site). I tried flushing cache and rebuilding permissions.
It happens with both APC and Memcache engines. I haven't got any problem with normal Drupal cache or the Memcache module, so I have switched to the latter.
