I did now several fresh installs of lightning. All without success. I also removed "WCAP Enabler" and disabled the aforementioned Google addon. I had a look through the profiles folder and saw the files disappear properly when doing the uninstall. Sometimes applications leave configuration files hanging around when uninstalling. This seems to be not the case for TB addons. So I reckon that the configuration was properly wipes as well during the uninstall. Unless it's stored somewhere else.
Anyway..... After a few fresh installs, I'm still left with an empty calendar view :(
