 Running nyx 2.0.4 from FreeBSD repository, after going to the
 'Connections' page which can be empty (AFAIK it depends on tor
 configuration), pressing a button which would normally lead to some useful
 information (eg 'd' or 'e') results in an unhandled exception and shuts
 nyx down.

 Key 'd' fails with:
 {{{
