This bug is applicable to both the GTK and the Qt interface, but both handle it
differently.

To reproduce, follow these steps:

1. Start a live capture
2. Click during the live capture on "Capture->Refresh interfaces"
3. Observe, that the capture keeps going and is not interrupted (this is
actually ok, and makes sense).
4. Restart the capture via the button in the menubar:

In Qt step 4 leads to "No interface selected", packets remain
In Gtk step 4 leads to a restart of the capture, but no packets will be
captured, additionally, the "Start Capture" button is not accessible.

Should the menuitem for Restarting the capture really be accessible during a
live-capture? Because, that would be the easy fix, to just disable the menuitem
during a live-capture and reenable it once the capture-file is closed.
