Yes, that behaviour would be ok of course but I'm not setting a contradicting filename
at all. The filename I'm setting matches the filter perfectly. Yet, whenever I call
gtk_file_chooser_set_filename() it seems that the filter combo box is reset. My filter
still appears in the combo box in the file chooser dialog but it's impossible to make it
the default by calling gtk_file_chooser_set_filter() prior to opening the dialog because
gtk_file_chooser_set_filename() always seems to reset the active filter.
