Not sure whether this is an issue or not. But I was facing it and I had to fix it with patch-work.

There's an exclude flag in rsync to fetch repo files from git into svn. Ref.

So what is this doing is; excluding all the assets folder from the repository; and not just the one which is required for banners & screenshots. For example, in my plugin; I'm putting my JS, CSS etc. into app/assets/ folder. Also I've used a few vendor libraries in which assets folder is used. So svn-push script ignores all these folders along with the one with banners; resulting in partial file uploads in WordPress.org SVN repo. And this eventually breaks the plugin functionality.

So what I did to prevent this is; removed the exclude flag for assets from rsync and after that I removed assets folder from svn trunk using rm.

Though this worked for me, I had a hunch that either I'm doing something wrong or missing something in order to use this script.

Suggestions ?
