main_ui.FileViewer.this(gtk.Builder.Builder).recurseOverDirectories(gtk.TreeStore.TreeStore,
gtk.TreeIter.TreeIter, immutable(char)[]) (this=0x7ffff7ed0800, path=...,
parent=0x0, store=0x7ffff7ecb100) at source/main_ui.d:69
69                                      TreeIter iter = store.append(parent);
