Actually it is probably worth mentioning that this is likely not a problem in
Maverick because dml-dove on Maverick is based on Lucid.

Which brings me to one more note: On future SRUs I would not mention the topic
branches at all if the problem is in a master tree. All those will get the fix
anyway when they are rebased. And it can be a pain to think of all of them. For
example Lucid-ec2 will be affected by this bug, too.

For branch specific SRU requests, I would include that in the subject, eg.

[lucid-mvl-dove] SRU: ...

At least to me this helps a lot to know at a glance what the target of a patch
is (which comes handy later when applying).

I have taken the liberty of extending the commit message by a bit more
explanation and applied and pushed it to lucid-master-next.
