I had the same error today. Data from my iphone was not synced back correctly on my mac after i woke up the mac from sleep.

I sought out the corresponding zip file and compared the different copies on my local disk an on the idisk. The local file was only half size and was corrupt (unzip was unable to open it) while the idisk file could be copied to my mac and opened without a hassle.

Thus i simply moved the good copy of the file into the OmniFocus.ofocus folder on the local disc and started OF.
So far everything seems to be fine, the changes i made on the phone are shown correctly on the Mac.

I'll try further syncing now....

Edit: Several syncs later everything is working fine so far. Holding my thumbs...
