Data not getting through for display

Hi.

Some background on how I am currently using graphite trunk/main.

I am using the bzr version of the code. I don't run any apps as root so I had to munge with carbon-agent to make it to accept command line parameters for various things like log dir and pid dir. I also had to munge with init-script.sh to insert variables to be replaced during build time. None of the changes modified any core code in any of the scripts.

I also had trouble with mod_python not agreeing with virtualpython about python-paths and despite help from our local pythonista, uttering a few magic incantations, I could not get it to work. So I hooked it up to mod_wsgi using Django's wsgi entry point as outlined in the docs (I have not used Django before so there's a possiblity that I messed up - but it does not look like it). Finally I switched from distutils to setuptools as its a bit more saner during build time. I also created the schema file per the docs and simply replaced the ^server\. with ^system\. to match the example script.

I finally got everything to work from a self contained folder. The graphite main page shows up. I then fired up the example-client with 10 sec delay and it goes its merry way. Django settings have DEBUG set to True. carbon-cache logs show data coming in fine. The whisper files exist for the metric. However when I search for the name of the metric or try autocomplete it fails with a 500 with nothing in the logs. CLI simply shows a black box with No Data in red. I am not quite sure what is wrong and before I dug into the actual app code itself, I was wondering if there are any obvious things I should try to figure out what went wrong. Log snippets are included below.

If you would like to take a look I would be more than glad to dump the tarball somewhere for download. Its ~31M with all the packages (Django, pyparse...) and 13M without.

Thanks.
