------- Additional Comments from Maxime BRITTO <mbritto at pleyo.com>
Comments about the fix :
This fix is preventing the crash without any visible unexpected effects (on
GoogleMaps and on the Layout Tests).
The check for the instance on the constructor is not essential but I think it
may be useful to prevent  future bugs which can look like this one. If the
reviewer don't like it he can remove it.

Comments about the test :
There is no test attached to this patch because we need to use tabs to
reproduce it and the DumpRenderTree doesn't handle them. If there is another
way to reproduce it I don't know it.
