IndexError: list index out of range on trac submissing

[strk@…]

I've found and fixed a bug in version 1.0.9dev of the TracSpamFilter plugin (the only one that I was able to install somehow). The bug is only exposed in new installs, while the spam clean procedure did not run yet. I think you can reproduce by deleting from the "system" table the entry with name = 'spamfilter_lastclean'.

Here's the patch:

Please let me know if there's a more recent version of the plugin I should be using instead. This is against Trac 1.0.5. Thanks.
