QShGetFileInfoThread never gets destroyed

Create a tree view with a QFileSystemModel. Upon painting a QShGetFileInfoThread is created in function 'shGetFileInfoBackground'

{{ static QShGetFileInfoThread *getFileInfoThread = nullptr;}}
{{ if (!getFileInfoThread) {}}
   getFileInfoThread = new QShGetFileInfoThread;
   getFileInfoThread->start();
{{ }}}

but this thread will never be canceled (deleted) anymore. Except a final call to 'shGetFileInfoBackground' times out!
