Priority: normal Component: ScrumBurndownPlugin
Severity: normal Keywords:
Cc: Trac Release: 0.12

Description (last modified by Ryan J Ollos)

How to Reproduce

While doing a GET operation on /burndown, Trac issued an internal error.

I downloaded and installed the plugin via easy_install and giving the SVN location as specified on the page.

This is what I did:

Doing subversion checkout from to
Processing scrumburndownplugin
Running trunk\ -q bdist_egg --dist-dir c:\docume~1\admini~1\locals~1\tem
zip_safe flag not set; analyzing archive contents...
Adding tracburndown 1.9.2 to easy-install.pth file

Installed c:\python27\lib\site-packages\tracburndown-1.9.2-py2.7.egg
Processing dependencies for tracburndown==1.9.2
Finished processing dependencies for tracburndown==1.9.2

C:\>trac-admin C:\trac\poc upgrade
Attempting to create the burndown table
Attempting to modify the milestone table
Upgrade of the Burndown plugin failed
Error message: (1264, "Out of range value for column 'due' at row 1")
Upgrade done

As you can see after running my environment upgrade I encountered this issue shown above.

When I tried to use the plugin via Trac get: TypeError: 'NoneType' object is not subscriptable.

Please see below for environment setting and python traceback. I have also attached my log file. Please advise.
