Good work, Moritz.

After fixing the obvious bugs:
	
	https://github.com/mwarning/PyQt4-Examples/pull/1

there's one problem left:

Clicking on copyrightnotice.txt should display the content of the file, as done in a fixed 
c++ example code, but it just prints:

	TypeError: invalid result type from FtpReply.readData()

The c++ code returns a -1, but QtCore/qiodevice.sip notes, that None is returned for the 
error case. I guess, this is true for the exhausted case, too.

I don't see any more obvious problems with your code, hence this might be a PyQt error.

Phil, if you want to take a look, you can pull from here:

	https://github.com/frispete/PyQt4-Examples.git

Run python main.py, and click on copyrightnotice.txt.

Cheers,
Pete
