Qt4 interface fails without X

When an interface cannot start, its Open() must return VLC_EGENERIC or some other error. Qt4 exits the entire process, so that VLC crashes whenever it's started without working X.

added Component::Interface: Qt Severity::normal Type::bug Version::master git labels

changed milestone to %0.9.0 features freeze

The code is there (line 179 of qt4/qt4.cpp) and is working on my box. Could you add some debug

With a non-working DISPLAY:

Still crashing exactly the same:
