To reproduce:
1. Open any file containing an InsetCommand-type inset, e.g. a label.
2. Select some material containing that inset.
3. Exit LyX.

The offending line seems to be:
vector<int> const & view_ids = pimpl_->application_->gui().viewIds();
I think what's happening is that the material saved in the selection is
not being destroyed until too late. The global pimpl_ seems already to
have been destroyed at this point--I think because this is all clean-up
being done by C++ itself. So somehow it seems we've forgotten to destroy
the cache of copied material.
