An update. I have installed the apt source and rebuilt with debugging symbols.
I looked at apt_0.7.23.1/methods/cdrom.cc and saw Debug::Acquire::cdrom, so tried setting Debug::Acquire::cdrom "true" ; in a file under /etc/apt/apt.conf.d/ I also tried running /usr/lib/apt/methods/cdrom under gdb but was unclear whether arguments (I tried full-upgrade) were needed and how the return was handled. So far I have not managed to triger the segfault, although I am still seeing errors from aptitude when it uses cdrom to read dvds. Also I have not seen any extra errors reported via Debug::Acquire::cdrom - I am not sure where they should appear. Just to stderr, and/or somewhere in /var/log/? I see references to Udev in the source code and note that the recent udev rules do not always identify cdroms and dvds correctly (bug reported). But I think the apt dvd segfault predates that change, so perhaps no connection, although even then a segfault obviously isn't exactly desirable :-( ael -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
