Steps to reproduce the problem:
1. Open Chrome
2. Sit around and wait for a seemingly-random amount of time (5-45 minutes).  Duration doesn't seem to be dependent on browser use/activity.
3. Watch Chrome suddenly crash.

What is the expected behavior?

What went wrong?
Chrome crashes.  It's become a pretty persistent thing since it started doing it to me yesterday on a completely different machine (Windows 7 on that one).  I've disabled all extensions and it still persists.  At this point I have numerous Crash IDs for this, the one assigned to this post is just the most recent one that uploaded at the time of this writing.

Crashed report ID: Crash ID ed815363-da57-4934-bd19-0667ecfb75a6 (Server ID: aef98cf700000000)

How much crashed? Whole browser

Is it a problem with a plugin? No 

Did this work before? N/A
