I am unable to reproduce this, Ingeborg. I have psycopg2 2.4.5 and PostgreSQL 9.1.14.
Only thing that might help is setting DJANGO_DEBUG=True in `nav.conf`, provoke the error and dump a proper traceback from the web page, with the local vars of at least /usr/local/lib/python2.7/nav/report/dbresult.py line 49.
