We've seen this error occasionally but reproducing it has been hit or miss. I'd advise filing an issue on the googleappengine issue tracker <https://code.google.com/p/googleappengine/issues/list>and uploading a sample app which exhibits the problem. If you provide a link to the issue I will pick it up from there.
