Package: cheese Version: 2.30.1-2 Severity: normal
When the user has access rights to /dev/video0 then cheese runs correctly: $ ls -la /dev/video0 crw-rw----+ 1 root video 81, 0 Jun 5 00:14 /dev/video0 $ groups nmarci dialout cdrom floppy audio dip video plugdev $ cheese Whent the user has not the necessary rights then cheese crashes with segmentation fault right after startup: $ sudo chmod 600 /dev/video0 $ ls -la /dev/video0 crw-------+ 1 root video 81, 0 Jun 5 00:14 /dev/video0 $ cheese Segmentation fault My first investigations leaded to cheese_camera_create_camera_source_bin() function in libcheese/cheese-camera.c , where the library function gst_parse_bin_from_description() is called. I guess this library function shall return NULL if an error occured, according to http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstParse.html#gst-parse-bin-from-description . As far as my investigations gone so far the function gst_parse_bin_from_description() does not return NULL when the /dev/video0 is not accessible. Later on this causes segmentation fault in cheese. -- System Information: Debian Release: 6.0.1 APT prefers stable APT policy: (500, 'stable') Architecture: i386 (i686) Kernel: Linux 3.0.0-rc1 (SMP w/2 CPU cores; PREEMPT) Locale: LANG=hu_HU.UTF-8, LC_CTYPE=hu_HU.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages cheese depends on: ii cheese-common 2.30.1-2 Common files for the Cheese tool t ii gstreamer0.10-plugins- 0.10.30-1 GStreamer plugins from the "base" ii gstreamer0.10-plugins- 0.10.24-1 GStreamer plugins from the "good" ii gstreamer0.10-x 0.10.30-1 GStreamer plugins for X11 and Pang ii libc6 2.11.2-10 Embedded GNU C Library: Shared lib ii libcairo2 1.8.10-6 The Cairo 2D vector graphics libra ii libcanberra-gtk0 0.24-1 Gtk+ helper for playing widget eve ii libcheese-gtk18 2.30.1-2 A tool to take pictures and videos ii libdbus-glib-1-2 0.88-2.1 simple interprocess messaging syst ii libgconf2-4 2.28.1-6 GNOME configuration database syste ii libglib2.0-0 2.24.2-1 The GLib library of C routines ii libgnome-desktop-2-17 2.30.2-2 Utility library for loading .deskt ii libgstreamer-plugins-b 0.10.30-1 GStreamer libraries from the "base ii libgstreamer0.10-0 0.10.30-1 Core GStreamer libraries and eleme ii libgtk2.0-0 2.20.1-2 The GTK+ graphical user interface ii libgudev-1.0-0 164-3 GObject-based wrapper library for ii libpango1.0-0 1.28.3-1+squeeze2 Layout and rendering of internatio ii librsvg2-2 2.26.3-1 SAX-based renderer library for SVG Versions of packages cheese recommends: ii gnome-icon-theme 2.30.3-2 GNOME Desktop icon theme ii gvfs 1.6.4-3 userspace virtual filesystem - ser cheese suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
