Bug#1104298: Apologies, had not noticed that bug 1090964, same problem, is closed with fix.

[billiardmarker]

See subject.

I had found bug report 1090964 by web search and not by Debian bug 
database tools which I hadn't used before, so was working from obsolete 
information. I'll know better in future.

Apologies again for wasting your time.
