This problem is due to the fact that your installation most likely has two entries in "cr_text". It should be only one (or so I presume from the rest of OpenACS code).
I don't know why cr_text exists and how you could have ended up with two rows in your code. I can tell that cr_text does not allow inserts (there is a trigger) so my assumption is, that it really only exists with one row which is empty (or could be updated).
OCT, could some of you please verify that my assumption about cr_text is correct?
