I had the same problem, and I discovered that this was because a locally-installed copy of the Google Provider plugin was installed in addition to the package "xul-ext-gdata-provider". The local version was version 0.13 while the Ubuntu package was at 0.16. However, the local version of a plugin is given priority by Thunderbird, so it was using version 0.13. The solution: click the "Remove" button for the Google Provider plugin and restart Thunderbird. You should now be using the version supplied by your package manager (0.16). You can tell which plugins are provided by the package manager, because they will not have a "Remove" option.
