Issue 3939: Regression: Browser crash with drag and drop
http://code.google.com/p/chromium/issues/detail?id=3939

Comment #2 by [EMAIL PROTECTED]:
This crash reproduces with the following steps:

  1. Create a new tab.
  2. Drag that tab out.
  3. Attempt to drag either tab.

This crash started happening on ChromeBot runs between revisions 4153 and  
4159.  It's
been occurring consistently since then.

Looking at the revisions in that range, the only one that makes sense is  
4155:

Fix a couple of tab related bugs:

- moving the window while a tab is animating to its final resting position  
disem
bodies the tab
- it's possible to make a tab disappear while clicking on another tab while  
a ta
b is animating to its final resting position
