Pythoscope doesn't handle unicode objects well

[Michal Kwiatkowski]

Minimal example is to have a module with a function that returns a unicode object:

# module.py
def fun():
    return unicode('\xc3\xb3', 'utf-8')

After running a point of entry that called fun() Pythoscope will exit with the following error message:

...

ERROR: Oops, it seems internal Pythoscope error occured. Please file a bug report at https://bugs.launchpad.net/pythoscope
