Hi Markus, We experienced this with Gora a short time ago.
Hadoop 0.20.0 contains slf4j-log4j12.version 1.4.3 Nutch trunk contains the same library dependency @ version 1.6.1 You might be able to get round this by simply downgrading you Nutch or upgrading your Hadoop dependecy to match up. I think this is the simplest workaround. Let us know how you get on.
