To be honest you can run whathever you want as a second summoner spell. Although I wouldn't run Ignite since Karthus rarely makes good use of it (he lacks kill pressure early, and you shouldn't be using Karthus against sustain-based champions like Vladimir or Swain, also Ignite doesn't help him against assassins which are one of his main counters)
