Hmm.  Try applying the attached patch to "gtk/capture_dlg.c" (the change
is in CVS - as is a change to cause it to supply no list of interfaces
to the combo box in the capture dialog box, rather than to pop up that
message, if it can't manage to open any interfaces, so the user can at
least try to open the interfaces and see why it can't be done).
