Hi,

I hate those tons of abi_x86_32 packages as well.

This is also not solving your slot conflict, but why not:
  - Use a Windows VM for Skype
  - Use a small Linux VM for Skype (e.g. Debian)
and just redirect your webcam.

In this way, you don't mess up your system with 32 bit libraries. And,
of course, you don't know what skype is internally doing as it is
proprietary software and not famous for no bugs/vulnerabilities.

Cheers
  Ralf
