Yes I have that problem too. I just spent a weekend going through and editing about 300 images I took at an event Friday night. Normally I dump them to my Mac and work on them in Aperture. (BTW, only iPhoto for IOS has this problem, Aperature and iPhoto for OSX still work perfectly.) So this experiment has left a bad taste in my mouth for iPhoto IOS. And to add insult to injury, the same 54 photos uploaded to Flickr from iPhoto IOS perfectly.
Before coming here, I Googled the error message and found a lot of links about, all from IOS developers getting it over the years (not just recently) due to improper coding using the facebook apis.
Now I have to figure out a way to transfer my edited photos from the iPad iPhoto to my MacBook Pro in a reasonable amount of time so I can get them uploaded to the event host's Facebook page.
