SQLite Constraint Exception on seemingly non-application related stuff

I am creating a database table with version 1 and call a method from onCreate method of the helper class to populate it with the data from a text file .

I am getting following errors that seemingly have got nothing to do with the table I am creating / populating.

In short, I am at a loss to understand

UNIQUE constraint failed: shortcut_and_widget_previews.name, shortcut_and_widget_previews.size (code 1555)

What are these wideget preview and alarm clock (first line in the dump above) stuff that are seemingly causing these problems? How to overcome these?
