I don't have that try/catch block in my copy (0.7.x branch). Besides,
I confirm this is a bug/missing feature in firebug and not in qooxdoo:
with firebug disabled, I get the exception in firefox's "error
console" as expected.
I guess I'll use my workaround (unless somebody has a better
workaround to suggest) until the problem is fixed in firebug. Thanks
all for your answers.
