The original reporter said he was running gwibber 3.1.0, which must have come from the daily builds PPA. However, the latest version in that PPA is now 3.1.6+r1180~natty1 which doesn't use any of the code paths mentioned in this bug report. Please ensure you are using the latest version in the PPA. However, I would highly recommend natty users downgrade to the official natty packages.
