I try view a DVD disc with VLC and Totem on Arch Linux. For some reason the

It's not clear to me that the crash actually happens in libdvdread.
Without a back trace it's impossible to be sure, but assuming the
DVD is http://www.imdb.com/title/tt1217209/ which looks like a
somewhat recent Disney title, I'd speculate that this is a
dvdnav_describe_title_chapters() issue.
It's possible that opening the DVD in vlc with the "No disc menus"
option checked works around the problem.
Applying the patches previously posted to this list might be
worth trying as well.
Yes, the disc is that one. I tried to view it with "No disc menus", but
a similar crash resulted. If you need more information, please, ask.
Like I already mentioned, properly analysing the problem requires
a back trace. This might require recompiling some packages:
https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces
If that's too much pain, you could try convincing the Arch Linux
packagers to optimistically back port the libdvdnav patches that
are floating around.
No, that's not too much pain. I added the following compile options to
the build scripts:
export CFLAGS="$CFLAGS -g -O1"
export CXXFLAGS="$CXXFLAGS -g -O1"
rebuilt the packages and installed them. Here is the resulting back trace:
