Second import finished without any errors.

After making the change on LiveJournal that I mentioned in a previous post and starting a second import, importing of both entries and comments completed without a problem. All the entries that I'd already imported and edited (mostly to fix Youtube embeds, though I still have a ton more of those to manually fix at some point) weren't affected by the second import, which is nice.

So yeah, if you got a lot of errors during importing entries, you might want to try the above fix and do a second import. It'll still take another two or three days or so, but it might be worth it.
