Additional note:

It seems the page is successfully created/saved in the SQLite DB. The trouble occurs after the page is stored in the DB.

[Christopher Lenz]

Is this consistently reproducable for you? What front-end are you using (CGI, mod_python, tracd)?

I just tried here with CGI and mod_python and am not seeing the error.

[Christopher Lenz]

Oh, and if you're running mod_python, are you using a threaded MPM?

[Matthew Good]

Ok, I'm encountering a similar error under mod_python when I try to delete the last version of a page. I'll investigate further.

[Matthew Good]

The _pages attribute was renamed to _index in [1977], but a few occurrences were missed.

This is fixed in [2255]

I want to apologize here, I missed the feedback requests from cmlenz on this ticket. Sorry.
