Also missing vlc as dependency:
File "run_tribler.py", line 134, in <module>
window = TriblerWindow()
File "/usr/share/tribler/TriblerGUI/tribler_window.py", line 201, in __init__
self.video_player_page.initialize_player()
File "/usr/share/tribler/TriblerGUI/widgets/videoplayerpage.py", line 53, in initialize_player
self.instance = vlc.Instance()
File "/usr/share/tribler/TriblerGUI/vlc.py", line 2121, in __new__
return libvlc_new(len(args), args)
File "/usr/share/tribler/TriblerGUI/vlc.py", line 4694, in libvlc_new
_Cfunction('libvlc_new', ((1,), (1,),), class_result(Instance),
File "/usr/share/tribler/TriblerGUI/vlc.py", line 361, in _Cfunction
raise NameError('no function %r' % (name,))
NameError: no function 'libvlc_new'

When does the vlc error happen? vlc, along with its dependencies, is really big, I am reluctant to pull it as a dependency. Maybe we can get away with making it an optional dependency.

Looking at the tribler code [1] will handle vlc not being present.
On loading the vlc module [2] calls [3] which should raise OSError when libvlc is not located which will be excepted by [1].
On kertase's system it appears to have found a library but that library does not provide libvlc_new which triggers the error.

Added it as tribler doesn't seem behave well without it.

Sorry for the delay.
