What does the error "should point to a 'ir.ui.view', not a 'theme.ir.ui.view'" mean?

Question

I'm running an Enterprise update 12 -> 15 command-line and it keeps failing on the following error.
I've googled around, and I can't find any information on this type of error.
I've already uninstalled all third party themes and modules. I'm stuck. What does this mean and how do I fix it?
**For whatever reason, every time I paste the error into this window, it jumbles up the order of the words.  I don't know why this is happening so here's a screenshot of the error:

I just manually edited the database and it went through OK:
FIND row: SELECT * FROM ir_model_data WHERE name = 'blog_breadcrumb';

UPDATE row: UPDATE ir_model_data SET model = 'ir.ui.view' WHERE id = [the id from the results above];
