Adding report in Openoffice Report designer fails

[Khaled Blah]

Hi all,

I have installed OpenERP 6.1 on a Ubuntu 11.10 (oneiric) system using the debian package offered on the download page. On the client side I've tried both Openoffice 3.3 and LibreOffice 3.5 and both gave me the same result.

Using the Openoffice report designer extension I cannot add new reports. Instead I found the error message below in the log:
