[Bug 1101621] [NEW] TypeError: 'NoneType' on every kind of file upload

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

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.
