Crash in feed.js on_timeout

[smithsz]

I am using nano to follow a cloudant db and my code crashes repeatedly in the follow module.
File: lib/feed.js
This line of code causes the error. Seems like self.pending.request is null.
self.emit('timeout', {elapsed_ms:elapsed_ms, heartbeat:self.heartbeat, id:self.pending.request.id()});
TypeError: Cannot call method 'id' of null
at Feed.on_timeout (C:\workspace\myApp\node_modules\nano\node_modules\follow\lib\feed.js:46
3:98)
Could this be caused by wrong usage or is it a bug within the follow module?
