Description: Get rid of string exceptions.
 One of the changes brought by Python 2.6 is the removal of string
 exceptions.  A mass bug filing identified Epydoc as having potential
 problems.  I later spot-checked all of the exceptions in the code, and I
 believe this is the only one that we have to worry about.
