Apparently so.  Here's an excerpt from bltinmodule.c's CVS log:

----------------------------
revision 2.241
date: 2001/10/16 21:31:32;  author: gvanrossum;  state: Exp;  lines: +3 -1
SF patch #471852 (anonymous) notes that getattr(obj, name, default)
masks any exception, not just AttributeError.  Fix this.
----------------------------

and the Misc/NEWS file:

- getattr(obj, name, default) now only catches AttributeError, as
  documented, rather than returning the default value for all
  exceptions (which could mask bugs in a __getattr__ hook, for
  example).

So clearly, Guido intended to make this change.
