Unhandled exceptions in nyx

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:
