No handling of dragnet errors

[sally14]

While running minet extract report.csv > articles.csv, dragnet errors lead the extract program to crash :

Extracting content: 4484 docs [00:27, 173.25 docs/s]multiprocessing.pool.RemoteTraceback:

During handling of the above exception, another exception occurred:

The above exception was the direct cause of the following exception:

Thank you

Can you give the CSV line producing this error (you can use -p 1 to use only one CPU and process the file sequentially to make it easier to find the culprit).
