Comment(by AlexanderDreyer):
I manager to install gentoo-prefix on an old ppc to debug things further.
The most current polybori builds nicely on that prefix, but I can now
reproduce issue mentioned here:
https://bitbucket.org/brickenstein/polybori/issue/1/non-aligned-pointer-
being-freed-on-os-x when using wither ipbori or invoking ipython with the
following manual commands:
Python 2.7.2 (default, Aug 22 2011, 13:36:51)
Type "copyright", "credits" or "license" for more information.

%quickref -> Quick reference.
help -> Python's own help system.

Invoking plain python doesn't cause any trouble:
{{{

}}}
So maybe an ipython issue?
