Handle none gracefully (fix #567)

[tawanda]

I installed the git version with the fix #567 so

terminal.py:

      if word_chars:
           self.set_word_chars(word_chars)

still get this trace

/etc/gconf is a folder which i thought was the guake preferences folder and i deleted it, that's when all this pain began

[gsemet]

your installation seems bloated. Remove everything in gconf (gconf-editor > apps > guake) and reinstall

[tawanda]

I have done it, i now get a window with

Guake can not init

Gconf Error
Have you installed guake.schemas properly?

Manually installing the schemas with the following command fixed the problem

gconftool-2 --install-schema-file=/usr/share/gconf/schemas/guake.schemas
