New submission from Philippe: The extraction fails when calling tarfile.open using this archive: http://archive.apache.org/dist/commons/logging/source/commons-logging-1.1.2-src.tar.gz
After some investigation, the file can be extracted with gnu tar and bsdtar and the gzip compression is not the issue: if I gunzip the tar.gz to a tar and call tarfile on plain tar, the problem is the same. Also this archive was created most likely on Windows (based on the `file` command output) using some Java tools per http://commons.apache.org/proper/commons-logging/building.html from these original files: http://svn.apache.org/repos/asf/commons/proper/logging/tags/LOGGING_1_1_2/ ... that's all I could find out. The error trace is slightly different on 2.7 and 3.4 but similar. The problem has been verified on Linux 64 with Python 2.7 and 3.4 and on Windows with Python 2.7.
