Yes, this is a problem, because there are some cases where there is no
way to reliably communicate the error to the web browser. What Squeak
tries to do in this case is to open up a debugger in the image
(#callback: in SURequest and SUEvaluator), but it does not necessarily
work in other cases. Normally SUUpdater and subclasses
(SUAutocompleter, SUInplaceEditor) should somehow show an error
message, however the web browser might decide not display the response
(due to some JavaScript logic, style-sheets that are applied, etc.).
In this cases it usually helps to have a closer look at the response
in FireBug.
