Comment 13 Raphael Groner 2016-08-28 14:02:48 UTC 
It could be useful to know what message gets tried to be logged. Can you reproduce this crash?

Propably http://code.qt.io/cgit/qt/qtbase.git/tree/src/plugins/platforms/xcb/qxcbconnection.cpp#n594

594    if (Q_UNLIKELY(!m_connection || xcb_connection_has_error(m_connection)))
595        qFatal("QXcbConnection: Could not connect to display %s", m_displayName.constData());

... but that would mean $DISPLAY is not set properly or the like. Also it could be a bug in XCB or XLIB.
Comment 14 Raphael Groner 2016-08-30 16:49:16 UTC 
I suppose you mean tigervnc-server instead of vnc-server. vnc and tightvnc are both orphaned in favor of tigervnc. Reassigning to ask for help there.
