Ooh, an AgiloForScrum issue! The first in a long time :)

@rblank, thanks for the cc. We're doing what we can to keep bug reports low ;-)

@prochat, this sounds like a known bug in simplejson. If you are using the RedHat package from Fedora EPEL, make sure you have upgraded to 2.0.9-2.el5. If you compiled it yourself, you will have to patch it manually since the version that includes the fix (2.1) is not available for Python 2.4 — check ​https://bugzilla.redhat.com/show_bug.cgi?id=622835 for details.
