qmldump error - segv

Hi there again,

I am having problem with qmldump, I will give the output which shows the best where the problem lies

Code:

---

" Processing object QDeclarativeAnchorAnimation 
Error: qmldump SEGV

---

this is the error I am having, I found out that it lies somewhere in

Code:

---

qmlRegisterType<File>(uri, 1, 0, "File");                    // <------- HERE IS THE PROBLEM
    qmlRegisterType<FileBrowserModel>(uri, 1, 0, "FileBrowserModel");
    qmlRegisterType<FileVisualProperties>(uri, 1, 0, "FileVisualProperties");
    qmlRegisterType<FileVisualPropertyChunk>(uri, 1, 0, "FileVisualPropertyChunk");

---

because when I commented it out, qmldump finished with 0 exit code - no error detected.
I do not understand where is this problem.
I will give the header file of this as well

Code:

no pointer anywhere, but it stuck on processing the animation...what is going on ?

Little update

I made a mistake writtin, in the previous post, that error comes out from File Item.

It's origin lies in the class which inherits both from QAbstractListModel, QDeclarativeParserStatus.
As to the interface I have appropriate macro Q_INTERFACES in class body.
The item is not drawable.

Here is the header file

Code:

to be honest, I am trying to write the implementation of FolderListModel available at Qt docs, but instead of using obsolete QDir, I am trying to use QFileSystemModel
