At the end you can see:

"Some input polygons are overlapping each other.
If overlapping is not desired, the data need to be cleaned.
The input could be cleaned by snapping vertices to each other.
Estimated range of snapping threshold: [1e-08, 1]
Try to import again, snapping with at least 1e-08: 'snap=1e-08'"

Try importing with snap=0.01 or something like that (depending on the 
nature and precision of your data.
