Bug#783245: wx gui does not work properly under vnc

[Francesco Paolo Lovergine]

Package: grass
Version: 7.0.0-1~exp1
Severity: important

Using wxwidget GUI under VNC the add raster/vector tool does not show a
working pop-up window to choose a file, which renders the GUI almost unusable.
Just for information the same issue appears in the native macosx binary under
the latest OSX version. It is working under X11 natively, so it seems some
strange oddity in interaction between the GUI and the WX engine under some
specific environments.
