Reading an ods file (which is a zip file) (created by LibreOffice Calc 4.2) leads to the following error message:

Assertion violation: std::memcmp(_rawInfo, HEADER, ZipCommon::HEADER_SIZE) == 0 [in file "src/ZipFileInfo.cpp", line 93]

This breaks the "Decompress Single Files" example in the documentation when reading from the stream.
Note that Decompress is able to decompress the entire archive without a problem.
