Comment (by jdgrimes):

 [attachment:29527.diff] checks if the count is `NaN` before updating it.

 I'm not sure why this happens, but I have a hunch that it is caused by the
 update count being empty when the page is loaded. That could happen if the
 updates transients were to get flushed, and the update APIs didn't respond
 with any updates. In my case, I think that might be happening because I
 was testing a custom API for retrieving updates for a plugin. I enabled it
 to get the update, but I disabled it again before running the update.

 So, it's possible the only way that a user could cause this is if they are
 hacking around with stuff. On the other hand it's a rather trivial patch.
 I'll leave the decision on whether it's needed up to y'all. :-)
