Bug#369913: 0.1.1-6 with libdvdread3 0.9.6-1 does not "dvdbackup"

The problem is that libdvdread3 is compiled with -D_FILE_OFFSET_BITS=64, and dvdbackup wasn't in this version. So copying from a libdvdread off_t to a dvdbackup off_t had interesting side effects, like scribbling all over random bits of memory. There was already a bug report open about it (#366092) but for some reason I had left it at severity important instead of grave, as it should be, so maybe you didn't see it. This is fixed, but stuck in the NEW queue (http://ftp-master.debian.org/new.html). Ordinarily this has been processed reasonably quickly, but I think the people handling it are on vacation right now, so things are moving slowly. Sorry for the inconvenience. I am not sure what I can do about this, but I'll ask around. -- - | ,''`.Stephen Gran | | : :' :[EMAIL PROTECTED] | | `. `'Debian user, admin, and developer | |`- http://www.debian.org | - signature.asc Description: Digital signature
Bug#369913: 0.1.1-6 with libdvdread3 0.9.6-1 does not "dvdbackup"
Package: dvdbackup Version: 0.1.1-6 Severity: grave After upgrading to 0.1.1-6 with libdvdread3 0.9.6-1 running $ sudo dvdbackup -i /dev/device -I just segfaults and when trying to mirror a DVD $ sudo dvdbackup -i /dev/device -o . -M it dumps between 0 and 400 MB of the DVD (depending on the DVD tried, both DVD-5 and DVD-9). When some data is dumped, most of the files seem physically present, but are only a couple of kB. Downgrading dvdbackup to dvdbackup_0.1.1-5_i386.deb libdvdread3_0.9.4-5.1_i386.deb "solves" the problem. Since playing a DVD with libdvdread3 0.9.6-1 is just fine, maybe the sync between the new libdvdread3 and the minor change in dvdbackup is off (new APIs?). -- System Information: Debian Release: testing/unstable APT prefers unstable APT policy: (990, 'unstable'), (700, 'experimental'), (500, 'stable') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.16 Locale: LANG=en_GB, LC_CTYPE=en_GB (charmap=ISO-8859-1) Versions of packages dvdbackup depends on: ii libc6 2.3.6-9GNU C Library: Shared libraries ii libdvdread3 0.9.6-1 Simple foundation for reading DVDs dvdbackup recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
