The file chooser loads folders asynchronously.  So, when you call
gtk_file_chooser_set_filename(), it will

1. queue an operation to load the folder corresponding to your file

2. go back to the main loop

3. once the folder is loaded, it will actually select the file

4. it will emit "selection-changed"

Sometimes the signal is emitted more than once, depending on the loading
state of the file list.
