Bug description:
   vlc will hang when trying to open anything additional -  it also appears to crash unity-window-decorator among other things (have crash report on that)
  Ex.'s - the playlist, tools > preferences and so forth

  Switching the qt4 gui to anything but 'default' (gtk+) in qtconfig-qt4
  and it works without incidence (tooltips are empty bit otherwise
  good).

  Will attach xsession.errors, reflects a login, opening vlc, opening xsession.errors, then attempting to open playlist window in vlc.
  (using nvidia-current)

  Note to Vlc users - I've found clearlooks to be best choice, should be
  good for other apps as well. Also do as mentioned in comment 13

  Note to Anki users - please review comments 20, 22 for current
  workaround

  This happens with many Qt4 and PyQt4 applications.
  Some errors displayed (from comments 16 and 18):
