Strange problem with guake in F15/KDE

[Alexander Volovics]

I have a problem with guake in F15/KDE that I don't know how to solve.
Can anybody help?

In whichever of the following two ways I start guake 
-typing guake after 'Alt-F2'
-clicking on the guake icon
it allways opens with the following prompt:
[ander at localhost Documents]$ 
instead of
[ander at localhost ~]$

However when I start guake by typing guake in a terminal it
takes on the location I was already in, thus:
'[ander at localhost ~]$guake' opens in [ander at localhost ~]$
'[ander at localhost Pictures]$guake' opens in [ander at localhost Pictures]$
 
How can I change the 'Alt-F2'/'icon click' behaviour so that
guake allways opens in [ander at localhost ~]$
