Thanks, this is updated

Yes, because this eventually is caught here in GifImageDecoder.java:

                    try {
                        if (!readImage(totalframes == 0,
                                       disposal_method,
                                       delay)) {
                            return;
                        }
                    } catch (Exception e) {
                        if (verbose) {
                            e.printStackTrace();
                        }
                        return;
                    }


In this specific test file: I never expect an exception to be thrown, but one 
did come up when I was first drafting this test (because of my own error). It 
was hard to debug because it was unreported. I would prefer to leave these 
printStackTrace calls in, in case a developer someday makes a change and needs 
to see potential errors.

(Technically I could try to make verbose `true`, but that's declared as a final 
variable and I don't want to modify GifImageDecoder.java just for this.)

Yes, this is caught in the same place the other one is (
