Package isn't removed if it is a source package

[Removed by request]

I'm using Ubuntu 13.10 dev with apt 0.9.9.1~ubuntu3. If a package gets requested to be removed but it is a source package apt does point then to the correct package. But this will cause that the package doesn't get removed anymore:

sworddragon@ubuntu:~$ sudo apt-get remove flashplugin-nonfree

After this operation, 139 kB disk space will be freed.
