When you upload using the chunk-feature and set stash=1 (or whatever) and then try to publish the file, only the contents or the first chunk are published.
In the next post, I will show the problem. You can easily see it in the results: The filesize of the upload is size="5402673" before publishing and size="1048576" after publishing.
I think one could simply ignore the stash parameter if chunk contents are set.
