vlc crashed with SIGSEGV in MainInterface::showTab()

[D]

FIrstly, for some reason there are two VLC windows. One shows the actual video, another window whos the initial screen information. There are actually two pane windows for a single video.

The second problem occured when Ubuntu 12.04 shows a crash report for VLC crashing after being left a lone.

This bug was fixed in the package vlc - 2.0.2-1

---------------
vlc (2.0.2-1) unstable; urgency=medium

  [ Edward Wang ]
  * New upstream release (Closes: #679625, #664279, LP: #689122, #936488,
    #942126, #971106, #972615, #973051, #987231, #995003, #998538).
    - Fix Ogg Heap buffer overflow. Thanks to Hugo Beauzée-Luyssen
  * Add the crystalhd plugin to the vlc distribution.
  * libcaca_plugin.so now depends on X11 in this release, so it must
    be installed under vlc (versus vlc-nox).

  [ Reinhard Tartler ]
  * Urgency set to medium because a security issue is fixed in this release

  [ Benjamin Drung ]
  * Add new plugins to vlc-nox:
    - crystalhd (Linux amd64 and i386 only)
    - directfb
    - fbosd (Linux only)
    - omxil (Linux only)
  * Add build dependencies for new plugins.
  * Add new symbols to libvlccore5.
  * Switch to debhelper 8.
