multimedia/vlc: no graphical interface on FreeBSD 9 and 10

[O. Hartmann]

Since a while, vlc on my FreeBSD 10 and FreeBSD 9 boxes do not show a
graphical interface anymore. Compiling multimedia/vlc works, either with
the legacy gcc or clang. But either way I compile vlc, the result is
always the same: no GUI. Instead, I receive the below show message:

VLC media player 1.1.12 The Luggage (revision exported)

(hint: compile the qt4 plugin, and make sure it is loaded properly)
[0x802080a70] skins2 interface error: cannot instanciate qt4 dialogs
provider

I tried several times to recompile everything vlc depends on, but with
not success. I also tried to delete every configuration file vlc created
in the past and my now suffer from legzy options, but that hadn't any
effect - as far as I could catch each config file.

Is anybody out here having had the same or similar problem and solved it?
