One of these lines from
resolvconf-1.76.1/etc/dhcp/dhclient-enter-hooks.d/resolvconf look
promising for this kind of issue:

  28 if [ "$new_domain_name_servers" ] && [ "$new_domain_name" ] ; then
  32 if [ "$new_domain_name_servers" ] && [ "$new_domain_search" ] ; then
  40 [ ! "$interface" ] || echo -n "$R" | /sbin/resolvconf -a "${interface}.dhclient"

One possibility I can imagine to cause such an issue would be if the
DHCP server gives out strange values for either the domain name server
list or the domains itself.
