[Python-modules-team] Bug#573369: python-scrapy: view response in browser required at least python2.6

Package: python-scrapy
Version: 0.8-2
Severity: normal

I tried to use Scrapy interactive shell according to:

When you try to use:
   view(response)    : View response in a browser
in Python 2.5 it fails:


In [7]: view(response)
TypeError                                 Traceback (most recent call last)

/home/miernik/cf/src/uweam_scrapy/<ipython console> in <module>()

/usr/lib/pymodules/python2.5/scrapy/utils/response.pyc in open_in_browser(response)
    105     if '<base' not in body:
    106         body = body.replace('<head>', '<head><base href="%s">' % response.url)
--> 107     with NamedTemporaryFile(suffix='.html', delete=False) as f:
    108         f.write(body)
    109         webbrowser.open("file://%s" % f.name)

TypeError: NamedTemporaryFile() got an unexpected keyword argument 'delete'

According to http://bugs.python.org/issue6357
'delete' keyword argument is new in 2.6.
The 2.6 docs mention it as being new in 2.6:

tempfile.NamedTemporaryFile([mode='w+b'[, bufsize=-1[, suffix=''[, prefix='tmp'[, dir=None[, delete=True]]]]]])


    New in version 2.6: The delete parameter.

But this package of python-scrapy depends only on default python: 2.5, so it fails.

After installing python2.6 and starting the shell with it, it works.
