The script is fixed, but the RRD files are still brokenly configured.

Which is now the case:
http://people.debian.org/~glandium/bts/i/iceape.png
The big fall is not a huge bug closing, but only from using the proper
data.

I'm currently trying to gather data from the BTS itself, I hope to see
how it goes during next week.

The correct data is now gathered, but it doesn't solve *your* issue,
which is due to something else, actually: the ddpo data doesn't contain
anything for packages with no bugs. So while the RRD files are updated
when there are bugs, it stops being updated when they are all closed.

There are two possible solutions for this:
- Having http://udd.debian.org/cgi-bin/ddpo-bugs.cgi contain bug data
  for *all* source packages, including those that have no bugs.
- Insert zeroes in the RRD file for all those that haven't been touched
  by last data retrieval.

Does the QA team think the former should be done ?
