[Mediawiki-l] mwlib/Collection Error after Upgrade to MW 1.16.0

[Ross Xu]

Hi there,
My MediaWiki 1.15.1 was working well with the Collection extension and my own mwlib render server to create PDF documents.
Today, I just upgraded my MediaWiki 1.15.1 to MediaWiki 1.16.0. After the upgrade, I get "Render server error" when I try to download a PDF book.
The error message is very long, but it includes:
**********************************************
An error occured on the render server: traceback Traceback (most recent call last): File "/usr/lib/python2.4/site-packages/mwlib-0.12.10-py2.4-linux-x86_64.egg/mwlib/apps/render.py", ...
File "/usr/lib/python2.4/site-packages/mwlib-0.12.10-py2.4-linux-x86_64.egg/mwlib/apps/make_nuwiki.py", line 171, in make_nuwiki raise RuntimeError(str(val)) RuntimeError: [Failure instance: Traceback: exceptions.RuntimeError: login failed: {'login': {'cookieprefix': 'mediawiki_docs_', ...
**********************************************
 
Are there any known issues with the MW 1.16.0 upgrade and the mwlib/Collection?
Any idea is greatly appreciated,
