Where you using AJAX Search, Gadgets, Gears, or Maps when this happened?  I 
only see regular GWT code in the 
stack trace.

nope ... no gadgets, only GWT and GWT-Ext (TreePanel as widget of a Composite).

It's the same problem like it's described here: http://www.gwt-
ext.com/forum/viewtopic.php?f=8&t=2614 (more users found it earlier).

This is project is not GWT proper.  I'm marking this issue as invalid for the 
gwt-google-apis project.  You need 
to file this bug in GWT's issue tracker which can be found at: 
http://code.google.com/p/google-web-
toolkit/issues/list.
