We should set remote search to disabled by default in ItemSearchJob, as this 
code is not really tested, and also not required currently.
Obviously there is also an issue in searchtaskmanager that we should fix 
nevertheless.

I'll look into this this evening, but you can already work around this by 
disabling remote search if you want.

Cheers,
Christian
