Catch errors raised by user objects when accessing attributes....
Catch errors raised by user objects when accessing attributes. When analyzing the line with prefilter, we look into whether objects have a 'rewrite' attribute. While this is off-spec, we've seen in the wild objects that raise something other than AttributeError on attribute access. Now we catch all exceptions in this codepath. Closes #988.
