Comment 8 for bug 221038

After living with the problem for a while, I have come back with some more information. I have two computers, a Dell Dimension 8400 (which is what I've submitted the initial information above with) and a Dell Inspiron 600m. I've had the same problem on my Inspiron, but after I followed "Part A" of the instructions at http://ubuntuforums.org/showthread.php?t=789578, the problem never happened again. I've been using pavucontrol without any crashing issues!
