I've just had a quick poke about online and it seems that there are a number of similar errors that occur (although I couldn't find any with your exact numbers which struck me as strange). Most of them seem to be upgrading old sites to the newer versions of Magento. So if you are importing a site made on an older version of Magento perhaps that's the problem?
Otherwise you may have found a bug.
There is a thread on Magento forums that suggests clearing the cache (unless you were importing an old site I'd expect that won't be it but who knows?). Have a read all about it here.
After a bit more reading I have discovered that the errors thrown aren't actually that helpful. To debugg this issue it sounds like you will need to set up error reporting. It doesn't look too hard, have a look here.
Have you done anything at all?
