occasional Uncaught TypeError

I am occasionally getting:

Uncaught TypeError: Cannot read property 'up' of undefined 

 

Which seems... improbable and/or impossible.  Yet, chrome37 is occasionally reporting that error.  I will try to create a gist of the condition creating it.  Just wanted to report the oddity and see if there are any others or any ideas of what might be going on here.

 

Here is the full stacktrace (recent first):

That is indeed pretty odd. Do you have your own "tick" listener(s) set up somewhere? 

 

I can easily add a conditional block to avoid that error in the next release.
