(At least in my case) it's a SIGSEGV in libcdio (libcdio13:amd64
0.83-4.2ubuntu1), reproducable with the "cd-info" tool:
$ LD_LIBRARY_PATH=./lib/driver/.libs:./lib/iso9660/.libs gdb -q --args
src/.libs/cd-info /dev/sr1
Reading symbols from src/.libs/cd-info...done.
(gdb) r

This doesn't happen anymore/has been fixed in a later version, such as
the one packaged in Debian libcdio15:amd64 0.92-2.
Rebuilding the gvfs packages against that one (no source code changes
required), and installing these, the SIGSEGV then doesn't happen
anymore, and the audio CD can be mounted/played fine.
As there as been quite some churn in the CD-Text source code in libcdio,
I couldn't easily identify the actual change that fixed this issue.
Should libcdio15 be added to Ubuntu, and gvfs build-depend on that one?
** Also affects: libcdio (Ubuntu)
