dspace import metadata acknowledges changes doesn't apply them

Question

Whenever I try to import metadata to my DSpace repository, the same way I've always done it before, something strange happens.

First of all DSpace allows me to upload the correctly formed CSV files, then it actually shows me what changes where detected ("Pending changes are listed below for review") and asks me to review them.

Finally when I accept the changes I get a message telling me "No changes were detected".

Could somebody shed some light?

Things I have tried to no success:

• Restarting the Tomcat server
• Trying to upload different CSV files
• Using different users

Thanks a lot

UPDATE 03/10/2012

I have tried the commandline import tool and now I get this error:

Any clues?

Well, that last update lead me to google the error which quickly pointed me to: http://dspace.2283337.n4.nabble.com/Dspace-tech-Internal-System-Error-after-granting-licence-td3288317.html. Then it was just a metter of checking permissions for the collection, where I realized that DEFAULT_BITSTREAM_READ was set twice, giving the impression of DEFAULT_ITEM_READ also being enabled. After granting the DEFAULT_ITEM_READ permission to the "Administrator" group it was fixed.
