Package: tracker.debian.org Problem:Even a VERY experienced user cannot decide which package is responsible for an error. For example in XFCE and MATE (in Jessie) Video-DVDs are not recognized by the system - no icon on the desktop, no indicator message about a new dvd, no autoplay which is configured correctly (same with xubuntu 15.04). Is this bug already filed? There is no obvious way for me to find out.
