It states an error message :

This issue seems to have slipped through the cracks somehow. I came up with the attached patch that fixes the original issue mentioned above, as well as a segfault in the download path handling that was masked by the original problem.

The attachment "debdiff against aptitude 0.8.3-1ubuntu1" seems to be a debdiff. The ubuntu-sponsors team has been subscribed to the bug report so that they can review and hopefully sponsor the debdiff. If the attachment isn't a patch, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are member of the ~ubuntu-sponsors, unsubscribe the team.

Made a mistake in the previous patch. It should only affect logging, as far as I can tell, but I shouldn't break that either. Fixed the error, made a new debdiff - I'm sorry I wasn't more careful the first time around.

Thanks for the report, and for the patches! Instead of taking your debdiff as-is, I've merged your changes into the debian/patches/04_changelog file. Uploaded to zesty.
