In qtbase/src/corelib/io, files qstorageinfo_p.h, qstorageinfo_unix.cpp, and qstorageinfo_win.cpp, two of the method names are spelled incorrectly. The methods retreiveVolumeInfo() and retreiveDiskFreeSpace() should be retrieveVolumeInfo() and retrieveDiskFreeSpace(). These are internal private methods so it does not affect the public APIs, but it should be corrected.
