Bug Description

Sponsor-patch died horribly in the face of a broken changelog entry:

$ sponsor-patch -s 755954
sponsor-patch: https://launchpad.net/bugs/755954 has 2 Ubuntu tasks:
1) opendrim-lmp-powersupply
2) opendrim-lmp-powersupply (oneiric)
To which Ubuntu tasks do the patch belong? 2

IndexError: list index out of range

The changelog in question had no spaces before the first bulleted item. Don't know if this is something you want to catch. Using -e worked here, so maybe an error like this should drop the user into a shell to fix the source package?

sponsor-patch shouldn't crash. It should tell the user that the changelog entry is malformed and ask the user to fix it.

Committed a fix to this bug. If you want to add a check for a malformed changelog entry, something like this should work:
debian.changelog.Changelog().parse_changelog(open("debian/changelog"), max_blocks=1, strict=True)
