I'll check that. Thanks for the bug report.

I don't understand how this can happen. In process_request(), get_diff_options() is called unconditionally, and the diff_opts dict always contains a "contextall" key.

Can you give us the Trac revision that you are running? Your setuptools stripped it (you may want to update setuptools, too).

Could you also try disabling all your plugins and try to reproduce the issue? If it disappears, add each plugin one at a time, and retry, until you find the faulty plugin.

No news, closing. Please reopen if you can reproduce the issue with all plugins disabled.
