Comment (by zooko):

 Could you please run this single unit test that fails --
 {{{allmydata.test.test_cli.Backup.test_backup}}} -- with the
 {{{math.log(10)}}} in place, under valgrind?

 http://valgrind.org

 Valgrind is very good. You'll need to use the Python suppressions file
 with it:

 http://svn.python.org/projects/python/trunk/Misc/valgrind-python.supp

 Another idea suggested by Riastradh on IRC is to turn on floating point
 exceptions: http://docs.python.org/library/fpectl.html
