Public bug reported:
I successfully imported a large music library (~310 GiB in ~64000 files)
into vlc 2.2.0~pre2-4build1 on a Lubuntu Utopic amd64 system, listened
to music for a while, left and returned to my machine a couple hours
later, closed vlc, reopened it (seeing that my imported music was still
listed), then closed it again. At some point after I got back to my
machine, vlc crashed, but I don't know when since the only reason I know
a crash happened was that Apport told me. I suspect the crash occurred
when I closed vlc the second time, though it may have been when I closed
vlc the first time, or at some other point.
Hopefully the automatically attached stack trace will provide useful
information.
