How exactly do you disconnect your kobo, and how long do you wait before deciding that processing has frozen? Processing can take a LONG time, particularly if you've added many or complex books, and it can pause on a particular percentage for quite a while. If corruption is occurring when you disrupt the Processing process, I'm not surprised.
This is difficult being spread across threads, but I haven't seen any direct clear confirmation from you yet that you have signed out from your Kobo acconut on the device (as opposed to "disconnecting"), and then logged back in again? In Settings > Accounts.
