Shotwell tries to import OGG pure audio files
On Ubuntu 20.10 with master, the video thumbnailer fails with:
(shotwell-video-thumbnailer:18660): GdkPixbuf-CRITICAL **: 09:16:47.196: gdk_pixbuf_save_to_callbackv: assertion 'GDK_IS_PIXBUF (pixbuf)' failed
(shotwell:18556): GdkPixbuf-CRITICAL **: 09:16:47.202: gdk_pixbuf_loader_write: assertion 'buf != NULL' failed
This is because it tries to import OGG audio files as videos.
