* Problematic condition
  kernel version: 2.6.26
  makedumpfile version: 1.2.7

* Successful condition
  kernel version: (SLES kernel)
  makedumpfile version: 1.1.4 (SLES 10 SP2 version, but in fact that is
                               1.1.4 although -v displays something
                               different ;-))
