The error message is (Firefox 4.0 and Chrome 12.0.712.0):
[Ext.ClassManager] Cannot create an instance of unrecognized alias: reader.tree
I have attached a reproduction test case of the issue: Same code side-by-side,with the only change being that in 'index-pr4.html', ExtJs 4 PR4 is used, and in the other, 'index-pr5.html', ExtJs PR5 is used.

Reason: Draw attention to attached test case.
