Hmm... strange. Here's the code from mainloop:

       funcs = self.pete.testfuncs()
       random.shuffle(funcs)

funcs should just be a list of about 30 or so strings. Try
printing it out instead of shuffling:

       funcs = self.pete.testfuncs()
       print funcs
       #random.shuffle(funcs)


Now, in random.shuffle:

       for i in xrange(len(x)-1, 0, -1):
           # pick an element in x[:i+1] with which to exchange x[i]
           j = int(random() * (i+1))
           x[i], x[j] = x[j], x[i]

where x is the list to shuffle.


To me this looks like a problem with your python installation.
I remember seeing a few weeks ago people reporting some weird
stuff between python gentoo and glibc.

What happens if you do this:

14:21 >python
Python 2.2 (#1, Jan 23 2002, 06:46:11)
[GCC 2.95.3 20010315 (release) [FreeBSD]] on freebsd4
Type "help", "copyright", "credits" or "license" for more information.

Strange that it would just show up now. Did you recently upgrade
your gentoo or python?
