As far as I know this bug was fixed recently in Quantal, and the latest version available in the archive (0.6.0.0) addresses this issue.

Closing as Fix Released.

I'm mixing this up, I think; I'll mark this as a duplicate of bug 1015328 instead, which seems more appropriate (and I'll upload the fix to THAT incessantly).
