compiz crashed with SIGSEGV in unity::dash::ScopeProxy::Impl::OnScopeActivateCallback()

[Sami Jaktholm]

Steps to reproduce:
1. Open music lens
2. Search for anything
3. Try to preview an online result from "Songs" category.

There's no crash when previewing a local result. The results causing the segfault seem to come from SoundCloud.
