Has anyone experienced any issues with encrypted time machine backups? On my iMac it took +3 hours to backup 1,15 GB of data before I canceled the operation. Activity Monitor shows 90 GB of sent data, very weird. The sparsebundle is only about 130 GB and it's a new backup (deleted the old sparsebundle because I thought something was wrong with it when I've experienced the same issue several times now). It seems that sometimes time machine decides to backup the whole partition from scratch, even though only 1,15 GB of data has been altered 
I'm using the latest generation Time Capsule and a i7 iMac late 2009.
Anyone with similar problems? I believe the issue has to do with the encryption, most likely a software bug in Mountain Lion (haven't tested time machine without encryption under ML yet).
Edit: same problem on both 10.8 and 10.8.1
