I've got something very comparable: "nautilus crashed with SIGSEGV in gnome_desktop_thumbnail_factory_generate_thumbnail()". I think it is best to add my info
When creating an empty image file, the thumbnail-function gnome_desktop_thumbnail_factory_generate_thumbnail() makes Nautilus crash. This error is only given when running nautilus as root, as normal user it just crashes without any message. To get this error: - open Nautilus - go to your home-directory with Nautilus - create an empty jpg or png in your home-directory ("gedit file.png" and then save this file) - wait up to 3 seconds - Nautilus crashes >From what I read form the code, it seems not to check if data-size is 0 (gdk_pixbuf_get_byte_length is not used), or gets a non-zero width and length. See https://developer.gnome.org/gdk-pixbuf/stable/gdk-pixbuf-The- GdkPixbuf-Structure.html#GdkPixbuf for documentation and https://github.com/GNOME/libgnomeui/blob/master/libgnomeui/gnome- thumbnail.c for the source. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1203349 Title: nautilus crashed with SIGSEGV in _gdk_pixbuf_new_from_uri_at_scale() Status in “nautilus” package in Ubuntu: Confirmed Bug description: Occurs when opening a folder that contains a video or audio file that is invalid or a 0 byte file.
