CSV Importer doesn't admit white spaces between the ',' and the next '"'

Steps to reproduce:

• Install Nuxeo CSV Importer

  $NUXEO_HOME/bin/nuxeoctl mp-install nuxeo-csv-1.6.3
  

• Config your import path in nuxeo.conf

  nuxeo.csv.blobs.folder=/tmp/nuxeo-csv-import
  

• Create a Custom type, e.g. PRDTPicutre
• add a XML extension

  - Upload 
  <require>org.nuxeo.ecm.platform.actions</require>
  <extension target="org.nuxeo.ecm.platform.actions.ActionService"
    point="filters">
    <filter id="importFile" append="true">
      <rule grant="true">
        <permission>AddChildren</permission>
        <type>PRDTPicture</type>
      </rule>
    </filter>
  </extension>
  

• Upload some files to your import folder
• Reload your config
• Try to import this csv file:

  "name","type","dc:title","file:content"
  "317180_-_images_-_products_-_13227079_-_templ1.jpg", "PRDTPicture", "317180_-_images_-_products_-_13227079_-_templ1.jpg", "CanadianPeak/317180_-_images_-_products_-_13227079_-_templ1.jpg"
  "317180_-_images_-_products_-_13227079_-_templ2.jpg", "PRDTPicture", "317180_-_images_-_products_-_13227079_-_templ2.jpg", "CanadianPeak/317180_-_images_-_products_-_13227079_-_templ2.jpg"
  

If your CSV file contains white spaces between , and " this error message is shown in the browser:

The type "PRDTPicture" does not exist

The same file without white spaces works ok:

"name","type","dc:title","file:content"
"317180_-_images_-_products_-_13227079_-_templ1.jpg","PRDTPicture","317180_-_images_-_products_-_13227079_-_templ1.jpg","CanadianPeak/317180_-_images_-_products_-_13227079_-_templ1.jpg"
"317180_-_images_-_products_-_13227079_-_templ2.jpg","PRDTPicture","317180_-_images_-_products_-_13227079_-_templ2.jpg","CanadianPeak/317180_-_images_-_products_-_13227079_-_templ2.jpg"
