I re-tested in preparation for submitting the bug to Debian, and the problem has disappeared. Something has changed in the 10 months since my report, the package is still Version: 1.0-6ubuntu0.1, but plenty of other packages on the system have been updated. As there is no way of reproducing and investigating the root cause, I'm marking it as Invalid.
