IndexError: list index out of range

[kelvin@…]

I get this error whenever I load the main page of the Wiki.

Any idea what is going wrong here?

This looks like an issue with the ​th:RevtreePlugin at the first glance.

Please report this issue to the plugin maintainer (that would be me ;-)) on the plugin web site, that is ​http://trac-hacks.org

Do not forget to copy and paste the traceback, but please take care to use verbatim block ({{{ }}}) as the traceback you've copied is mostly unreadable.

Replying to eblot:

but please take care to use verbatim block ({{{ }}}) as the traceback you've copied is mostly unreadable.

See also if you can copy and paste the text version of the traceback, not the pretty formatted one and report the version of Trac you use, including the SVN revision if you're using a development release.
