I would try to use bosspref and use the option to fix the user / disk permissions. If this does not work just sync all you info and restore / re-jailbreak. I know many here are all about restoring from backup after a restore but if you have a corrupted program there is a good chance the corruption will be restored if you do things this way. So just setup as new. It is very easy to re-sync all you info if you setup as new.
What did you install lately? Obviously you are doing something that iTunes doesn't like. I don't have this problem, actually, this is the first time I have heard of this. 🙄
