Hmmm. Well, it seems permission were the issue. If I write the images to the sd card, it now works with everything except Facebook.
Facebook raises a "file not found" exception. No other app (Gmail, Twitter, etc) has a problem. Anyone else seen this? I had a look in the source code for the standard Camera app, which shares fine to Facebook, but I couldn't see that they were doing anything special.
