The root cause is destructor of frmQuery dialog. It removes all
connection from combo box exclude last item - "new connection". Each
deletion invoke frmQuery::OnChangeConnection event and the
OnChangeConnection method invokes "new connection dialog" in the last
step. And because there are some empty combo boxes on this dialog, gtk
generates core.
My suggestion is disable event generation for cbConnection in the
destructor.
