I have a QDirModel in a QDirTree. I select several files in this view and try to delete them with with following routine:

Qt Code: 
  1. foreach(QModelIndex index,selectionModel()->selectedIndexes()){
  2. 	 if(index.isValid() && index.column()==0){
  3. 		if(dirModel->isReadOnly()){
  4. 		  return;
  5. 		}
  6. // Crashes here the second time.
  7. 		if(dirModel->isDir(index)){
  8. 		  dirModel->rmdir(index);
  9. 		}else{
  10. 		  dirModel->remove(index);
  11. 		}
  12. 	 }
  13.   }
To copy to clipboard, switch view to plain text mode 

The first file is deleted normaly, the second time the foreach loop is traversed the code segfaults in 'if(dirModel->isDir(index))'. The core tells me:

Qt Code: 
  1. #0  0x00002b2df126227c in QFileInfo::isDir (this=<value optimized out>) at io/qfileinfo.cpp:1059
  2. #1  0x00002b2df0040051 in QDirModel::isDir (this=<value optimized out>, index=@0x7fffbb797ff0)
  3.     at itemviews/qdirmodel.cpp:941
To copy to clipboard, switch view to plain text mode 

Maybe I am currently a bit boneheaded, but what is the problem here? this=<value optimized out>? I somewhat expected that the indices might get invalid when I delete a file from the list, but I am testing for that. The pointers are ok, since the first file is successfully deleted. Any ideas?
