mobile safari tries to sync (forever) icloud tabs

since i updated my iphone 4s to ios 6.1 i want to use the safari sync feature.

i configured everything (on phone & mac & no, i'm not in private surfing mode) and since i start mobile safari it tries to sync the data, but it never ends. the little sign next to the wifi signal is spinning and spinning. and that before i even typed a link in.

on my macbook pro (10.8.2, 17'', 2009, coreduo 3.06) i then get tons of error messages like this:

07.02.13 17:59:14,255 apsd[191]: <APSConnectionNotificationQueue: 0x7fad3b8bd490>: outstanding count -1 for com.apple.apsd-queue-port=com.apple.safaridavclient.push-user=501-env=productio n

i googled around but didn't find anything (of course i tried icloud safari sync on & of, restart safari, restart macbook, repair rights etc).

the strange thing is, with myupdated ipad (ios 6.1) bookmarks get synced (but open tabs not).

any helpful suggestions out there?
