I came across this problem of the lightning extension not working on a newly setup debian/etch machine. It would install the extension and seem to load it but it would not load any calendars or allow you to create a calendar. When creating a new calendar it would prompt you for the name but when clicking next nothing would happen. I originally thought it must be the profile I was using but after testing with a clean user it seemed that wasn't the issue either. I decided to try running sunbird on the machine since they are very similar apps and upon running it I got a useful error message!

error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

So it seems it was just missing the standard c++ library it needed. I ran apt-get install libstdc++5 and then uninstalled the extension and installed it again and now it works great.
