Undefined property in super dev mode / 2.6.1

[George Georgovassilis]

When using super dev mode with chromium on a rather simple project I stumbled over an exception about an undefined property - the only catch: the property isn't undefined. It happens somewhere down the road of a click handler, interestingly enough Window.alert(""+this) says 'undefined'.
