Export to PDF does not work

[H-Max]

Hi there.

First of all great module : saves a lot of time...

I have an issue while trying to export in PDF :

2014-06-06 08:36:10,748 32630 ERROR
openerp.addons.web.http.HttpRequest.dispatch: An error occurred while handling a json request
Traceback (most recent call last):

self.charset))
File "/usr/local/lib/python2.7/dist-packages/werkzeug/http.py", line 905, in dump_cookie
value = to_bytes(value, charset)
File "/usr/local/lib/python2.7/dist-packages/werkzeug/_compat.py", line 106, in to_bytes
raise TypeError('Expected bytes')
TypeError: Expected bytes

I have no idea where this is coming from...

Thanks to Hans I managed to solve this very issue downgrading the Werkzeug version to 0.8.3: pip install werkzeug==0.8.3
