As mentioned in the previous comment, the suggestion was that the bug was known and fixed in Thunderbird 3 tree.
Now that Thunderbird 3 (Lucid) has replaced Thunderbird 2 (Karmic) in main Ubuntu release, there seems little point in keeping this bug active.
Suggest bug is removed from the list of active bugs by janitor or next bug clearout.
