TypeError: 'NoneType' on every kind of file upload

[Yurif]

When I try to upload a file I get an error. It doesn't matter where I upload it. When I for example try to upload a file as mail attachment an error shows up in the upper right corner, when I try to attach a file via the document management system module it's just loading forever and nothing happens.

The error in the errorlog hover is always nearly the same:

The upload itself looks like it would work. In Chrome I see the progress for the file upload on the bottom left corner behaving normally and at 100% the openERP error shows up.

My first guess would be there are some file permissions missing but I don't really know were to start looking (my only try so far was to give the openerp user full access to /usr/lib/pymodules/python2.7/openerp/ and all subdirectories and that didn't change anything).
I installed openERP (7.0-20130118-002240) via apt-get from the repository at http://nightly.openerp.com/7.0/nightly/deb/ which was very painless but maybe is responsible for this.

Sorry if this bug report should be at the wrong place here.. I wasn't very sure where to put it.

Oh, I forgot to mention that my server is a Ubuntu Server 12.04.1 (GNU/Linux 3.2.0-34-generic x86_64).

Yurif,

You would need to install poppler-utils!

Thanks.

[Yurif (yurif)]

Thanks for the super fast reply! Problem solved :d

Thank you! I got the same problem with Openerp 7.0.
Now it works!
Best Regards.

Hi,
I thing that I got the same or similar problem, but it's not fixable with installing popper-utils.
At time it's impossible to attache a file to massages or prducts etc.

I'm running a Ubuntu 12.04 system with openerp 7.0 (trunk 04.02.2013)
