So the # is 12847.
Incidentally, you may want to download the latest release candidate
for 4.1.2, which has a number of changes and also a newer (and mostly
improved, very good for us) version of Maxima. This is at
http://sage.math.washington.edu/home/mvngu/release/upgrade/sage-4.1.2.rc0.tar,
or maybe there is even an rc1 somewhere now.

You may want to test things. I recommend testing at least all the
files under sage/calculus with this new code - see the developer's
guide about the syntax for sage -t.

These seem to be pretty closely related issues, so that seems
reasonable. Sometimes there are too many unrelated issues fixed on
the same ticket, which can be problematic, but this doesn't seem to be
the case here.
Thanks for taking the time to look into this!
