MySQL error when editing product in Magento

it's a v 1.4.1.1 Magento, upgraded from a v 1.3.2.4

When I try to edit a product an error message appears:

exception 'Zend_Db_Statement_Exception' with message 'SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '6028-0-2' for key 'PRIMARY''

And if I try to reindex prices I have the same message in exception.log

I think the problem is in the catalog_product_website table, because if I delete the row, I can run the price indexing, but as I try to edit the product to assign it a website, I get the same message.

A weird thing is that catalog_product_website table has only 2 columns, and the exception talks about a 3 primary keys table (right?)

Here is the whole stack trace:

I hope someone can help me, I really out of idea right now :(

edit: I've enhanced the exception log's message so I can see the whole query, and here it is:

It seems the problem is not in catalog_product_website table. The problem in price index table, maybe there some old records from previous version, that should be deleted. I would recommend you to reindex all the indexes. The full reindex process clears index table first and then it fulfill the table with data. It should help.

If full reindex is not helping, then it is possible that your installment has modules that observe prepare_catalog_product_price_index_table event, which modifies re-index select in a way of additional join that multiplies number of rows with the same primary key. It also may cause such an error.

As stupid as this sounds, since you are getting duplicated -- auto_incremented -- keys, have you tried incrementing your auto_increment value for that table? Assuming this is a conflicted DB state in some way, this would fix the issue. If you jump the PK by 100 and you still get PK violations, then the code is probably attempting to insert the same record twice.

This would be the relevant query:

ALTER TABLE catalog_product_website AUTO_INCREMENT=1234
