I'm finally back with an answer. A similar question came up which I've responded to here:

A: AnnotationHub: two broad peaks from same url are not the same

The file you had problems with was saved with the wrong file extension (.Rda when it was really a gff). It was one of a group of files with several problems either in how the data were processed or how the metadata were specified. I gave a more complete answer on the other post but the gist is that these resources were too dammaged to fix and have been removed from the hub. Similar resources are available via query().

Thanks for reporting this.
