Hi Jeff,

Sorry to have taken so long to respond to your question.  Vacations have left
us very short-handed, and we're not able to keep up with a growing backlog of
support questions, at least temporarily.
> Has anyone had a chance to verify whether this is indeed a valid bug?

Yes, I've just verified it.  Thanks for reporting this.  We also have a fix 
for it in Dennis's latest svn branch, so it will be fixed in 4.1.2-beta2 and 
the subsequent 4.1.2 release.  If you want the fixed version earlier, please
let us know, but in that case you'll have to check it out of our svn tree.
