Hi all,

Getting the following error from uwsgi error whenever I save anything. Any thoughts? All other preferences save fine if that helps.

interesting but unfortunately hard to say what's the actual problem.

Probably the best start to debug this is to modify 'pylons/controllers/core.py' (see the bottom of your traceback) and print out 'repr(kargs)' in line 90 or so.

INFO:root:repr(k): None, repr(v): u'tion: form-data; name="general.appearance_navigation_bar_color"\r\n\r\npurple'

So I tried to be clever (I'd prefer to share via git but I'm in a bit of a rush today) and went ahead and changed:

setattr(c, k, val) if k else logging.info(blah_blah)

and the line after that to dictionary comprehension that removes the None key:

args = {k:kargs[k] for k in kargs if k}

But then I get another traceback in a different module:
/home/lcssisadmin/mediacore_env/local/lib/python2.7/site-packages/WebOb-1.0.7-py2.7.egg/webob/multidict.py

So I modified, in _hide_passwd(items) I just added an if k statement to eliminate the None again, this time I ended up with assertionerror

Any ideas why mediacore is passing a "None" key that seems to be resulting in the error?

Modifying the Pylons or the base libraries is likely not the right solution but currently I don't have an idea why this might happen. I assume either your DB contains some bad data or you trigger a bug in MediaCore.

Can you try to initialize a new DB just with the default data? Does the error appear there as well?

Which version of MediaCore are you running (as exact as possible)? Did you modify the source code/are there any plugins active in your install?

u'tion: form-data; name=" could indicate some problem with data actually received from your browser. Just to be sure could you try to check if the form data in the post request looks good? (use something like wireshark, Firebug, Web inspector ..

You could also try to remove all '__before__' methods (though I suspect that will leave you just with a broken MediaCore).
