Description Jonathan Liu 2011-07-29 11:31:12 UTC 
Version:           1.7 (using KDE 4.7.0) 
OS:                Linux

https://github.com/taglib/taglib/blob/master/taglib/ape/apeproperties.cpp#L140.
A null FrameFactory pointer to ID3v2::Tag constructor. Later on when reading the tag, it crashes trying to dereference the null pointer. It should omit the null pointer argument so that the default FrameFactory instance is used.
