[Zope3-Users] error 500 on blob upload with testbrowser

[Christophe Combelles]

Hello,

I can successfully upload a zope.app.file.File with testbrowser,
but with zope.file.file.File (blob-based), I get this error 500:

----------------------------------------

Exception raised:
     Traceback (most recent call last):

I'm using:
     >>> 
browser.open('http://localhost/++skin++Rotterdam/@@+/action.html?type_name=zope.file.File')
     >>> browser.getControl(name='form.data').add_file(StringIO('rrrrrrttt'),
     ...                                               'text/plain', 'toto.txt')
     >>> browser.getControl(name='form.actions.add').click()

----------------------------------------
Is there something specific due to the blob?
I get the same error with testbrowser 3.5.0
