Code review comment for lp:~ampelbein/ubuntu/oneiric/libqtbamf/lp-765915

I removed the optional symbols because I consider it good practice to have a symbols file that actually matches the symbols of my library. I readded them now.

And at least in my pbuilder it is still an issue, the build fails due to wrong symbols file.
Also, libqtbamf1 was last built in natty (not oneiric), see https://launchpad.net/ubuntu/+source/libqtbamf/0.2.1-0ubuntu1. It shows as built because for natty the symbols file was indeed correct.
