If you're going to use popen(), you have to be prepared to handle how the utility you call sends data over that pipe. The bug is indisputably on the Python script side unless there's a spec tar claims to adhere to but doesn't. That said, I don't think it's an unreasonable bug. I certainly wouldn't think any less of a programmer who wrote it.
