I'm very happy with your Cairo Desktop Evironment. Thanks a lot for your great work!

Bug Description
But this morning I updated my Cairo Desktop installation to Version 0.4.164.51285.
Re-starting Cairo Desktop after installation lead to the following error:

Message: Object reference not set to an instance of object.
Target Site: CairoDesktop.AppGrabber.CategoryList.Deserialize(String ConfigFile)
[...]

Please see the attached screenshot for the details.

If I acknowledge the error dialog with "Yes" the same message just appears again.
If I acknowledge it with "no" the dialog disappears but nothing else happens and the process "CairoDesktop.exe" still keeps running in the background.

So I switched back to Version 0.4.158.53003 of Cairo which still works fine for me.
