Unable to sync my iPhoto albums (Mac) on my ios devices.

[Mamaw]

Since the Maverick update, iTunes is no longer able to sync my iPhoto albums (Mac) on any of my ios devices (7.03)
Everything was working well under Mountain Lion.

My setup is as follows:

- My iTunes and iPhoto libraries are on an external drive connected to an Airport Extreme.
- I access these libraries from a Macbook Air via wifi.
- iPhone or iPad are plugged in a usb port to the mac.

I also tested the following :

- Synchronize my photo albums on an old iPod Touch (ios 6.1.3), does not work.
- The albums synchronize correctly when I plug the external drive directly to the mac.

Any idea to solve this problem ?
