thanks for providing this patch, George.

@Mike#2: I know that the component owner concept is not yet in  
place... But do you feel like taking over bug triaging for X2Go Client  
completely (as offered in one of your previous mails). If no, please  
me (and others) no via x2go-project ML (because then we need to find a  
way of triaging X2Go Client bugs ASAP). If you still volunteer for  
this task, feel free to ping me for feedback whenever needed.

From now on, I will hold my feet still for incoming patches if they  
don't address pyhoca-gui, pyhoca-cli, python-x2go, x2gobroker or  
nx-libs. I will be so free and tag bugs with "patch" whenever I spot a  
bug that ships a patch.

Mike
