Yes, our CKAN runs under Apache. And I tried already with 
'X-CKAN-API-Key' header - but it seems to make no difference.

Ok, tried as well like this. No problem to create data sets without 
extras, but requests with extras hangs for ever :
In [96]: ckan_object.call_action('package_create', dict(
      name='simple-testtt',extras=[{'key': 'location', 'value': 
'extended data'}]))
..................... ?????????????

I tried it as well with the package requests from project
https://github.com/PyBossa/pybossa
but the behaviour is the same.

And as well I can se nothing in the ckan.log except :
2013-04-29 13:05:06,879 DEBUG [ckanext.spatial.model.package_extent] 
Spatial tables already exist
2013-04-29 13:05:07,183 DEBUG [ckanext.harvest.plugin] Using auth 
profile at ckanext.harvest.logic.auth
2013-04-29 13:05:32,209 DEBUG [ckanext.harvest.model] Harvest tables 
defined in memory
2013-04-29 13:05:32,212 DEBUG [ckanext.harvest.model] Harvest tables 
already exist
2013-04-29 13:05:32,226 DEBUG [ckanext.spatial.model.package_extent] 
Spatial tables defined in memory
2013-04-29 13:05:32,234 DEBUG [ckanext.spatial.model.package_extent] 
Spatial tables already exist
2013-04-29 13:05:32,564 DEBUG [ckanext.harvest.plugin] Using auth 
profile at ckanext.harvest.logic.auth

But this seems to be default messages, or ?

( Maybe I should point out that we installed the extension 
ckanext-spatial to allow geo-spatial faceted search.
Could this impact the generation of extras fields ? )

I really don't know what I shall do - but we urgently need to be filled 
this extras for our project !
So I'm very helpful for any help.

Thanks,
Heinrich
