Apologises for the delay of this response. I didn't have much time lately due to foreseen circumstances, I hope you understand.
I also didn't see through this bug completely and didn't interpret the symptoms correctly right away.
The file chooser dialogue is not a part of Nautilus, but of the GTK+ project. However, when using GtkFileChooserDialog, the VFS entries should be added correctly to the sidebar.
The bug you reported is in the GTK+ -- a graphical toolkit -- integration of Qt -- another graphical toolkit, called QGtkStyle. It tries to draw Qt applications with GTK+ and uses GtkFileChooser to draw the file chooser. This is where the bug lies.
