I'm using parse_buffer on a string derived from S3 via the fog gem. The content type is "application/vnd.ms-excel". It works if the file is local.

Hey Kurtis, did you manage to solve this? I am having the same issue.

@dmferrari : can you provide a minimal test case please?

[krainboltgreene]

It was a bit ago. Either I wasn't actually pulling down a document or the document IO was incorrectly being thought of as empty. I think it was the latter.

I probably forced them to export XML files.

@krainboltgreene , @dmferrari : give me a minimal test case so I can reproduce the issue. (I have access to S3 so I can upload the file, but I don't have time right now to write the test case myself).
