I found nothing helpful in it, but here's the whole thing anyway :

KGlobal::locale(): Warning your global KLocale is being recreated with a valid main component instead of a fake component, this usually means you tried to call i18n related functions before your main component was created. You should not do that since it most likely will not work

I was able to kill indiserver after several minutes, I think I'll use bash
ulimit next time to keep indiserver more manageable.

What can I try next ?
