Comment 3 for bug 1709706

I'm not aware of any work having been done on this, but it's possible someone did it without attaching it to this bug.

To verify if this is fixed, we would need to come up with an error (or hack the client to cause one) that raises an exception on the client-side and see if the resulting output in non-debug mode is useful. Historically, it was not because it just dumped out the exception message. In some cases this was completely worthless. The linked bug printed an empty string, and I know there was a bug at one point where it raised a KeyError that just printed the missing key. _Some_ kind of additional information is needed in such situations.
