I'm marking this as resolved, since one tester demonstrated it worked.

Thanks all for reporting and testing!

Regarding the migration to Backbone.js and Tastypie, it sure seems interesting.
However I don't think I have the time right now to look into it...

I confirm that my issue is solved. sarahsharp, can you confirm that it fixed it
for you too?

e2jk, also -- what I'd like to see in the long run is a re-working of all this 
to use Backbone.js for the frontend, and something like Tastypie for the 
backend. Then we'd suddenly have dramatically less code.

Fixing the issues for users right now is definitely important, so thank you for 
working on it!

I mention it in case you're interested in learning about those tools and helping 
with that migration... (-:

I have some personal bookmarks here on that topic: 
http://bookmarks.makesad.us/insipid.cgi?tag=backbone

Again, thank you for this patch; I'm amazed how short it is, and it seems to fix 
things for me, but I'd appreciate a second look.

e2jk, can you verify this is fixed against the live site now? I've deployed this 
change.

Sorry all for the delay.

I fixed the issue and created a pull request:
https://github.com/openhatch/oh-mainline/pull/54

It definitely fixes the issue I just mentionned, and hope it fixes sarahsharp's 
issue as well, but since I couldn't get a snapshot of the site working (see 
issue 757) I can not absolutely confirm this.

I have the same error message when trying to create a new project on 
http://openhatch.org/+portfolio/editor/

My username is e2jk.
In case this helps debugging, this is the information I tried to add:
Project name: FLOSS Talks
Description: This website provides you with a list of all the interesting 
podcasts and videos about your favorite open source projects.
My involvement: I started the project.

Whenever I click the "Save all projects" button or the "Save and publish" link 
in the lower left part, The spinner spins and the message about giving pox on 
the developers appear ;)

I tried creating a project with just the project name, or without a space in the 
name, some tries looked like they were going to succeed as the error message 
popped up after 5-10 seconds, but all those attempts failed.

Just as with sarahsharp, I suppose you can find those errors in the Django error 
log. I also tried a few days ago, both on Firefox 14.0.1 and Chromium 
18.0.1025.168 under Ubuntu 12.04.

I totally just saw the bug you hit in a Django error log message. I am sorry! And also we will take a look.

I created an account on openhatch, but I can't associate the kernel project with
my profile.  I go to
http://openhatch.org/+portfolio/editor/?add_project_name=kernel, but I can't
edit the description, or add text about how I've contributed to the project. 
I've tried clicking both the "Save all projects" button, and the "Save and
publish" button.  A "Saving, please wait" message pops up twice, then two
messages that say, "Oh dear! There was an error saving this entry in your
portfolio. A pox on the programmers." appear.  The spinner under "unpublished"
on the left side continues to spin, but nothing happens.

My username is sarahsharp, if that helps.
