<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Thanks for the review.
I decided not to add any docs yet, in case everything has to change.
I'll also fix the style issues after the non-style ones.</pre>

template<typename MetaObjectList>
bool parseOne( ..., MetaObjectList &objectList )
with dummy generic implementation (that can jast assert(false)) and actual things implemented in template specializations. Would save just a couple of declarations though.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">C-style casts are very dangerous in C++ code that uses virtual inheritance. (and you do because NepomukTrack inherits Meta::Statistics that inherits QSharedData virtually) (more occasions below, I won't repeat this)</pre>
