I had the same problem after upgrading from jaunty to karmic alpha 1 and added a comment on bug 380234 for this. But I'm not sure if the issues described there are exactly the same as the issue described here so I won't mark it as a duplicate. Instead I marked bug 383434 as a duplicate of this bug since this bug contains more information about the issue.
