[Zope-dev] 2.7 dies when downloading file

[robert]

Hi there,
I would be gratefull if somebody could help with the following:

calling the following piece of code lets Zope die.

    security.declareProtected(CMFCorePermissions.View, 'index_html')
    def index_html(self, RESPONSE):
        """ Produce a PDF for issue"""
        RESPONSE.setHeader('content-type', self.content_type())
        RESPONSE.setHeader('content-length', str(self.get_size()))
        RESPONSE.setHeader('content-disposition', 'attachment;filename=i%s' % 
self.getFilename())
        RESPONSE.write(self.getFile())


it produces the following traceback
