Comment 11 for bug 1268838

(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?
