Comment 0 for bug 269386

At the moment, BugzillaLPPlguin.fetchComments() passes dict(bug_ids=[...], ids=[...]) to the Launchpad.comments() API method on the remote Bugzilla. Instead, it should be passing dict(bug_ids=[...], comment_ids=[...]); `ids` is out of date; `comment_ids` is the correct parameter name.
