Thanks a lot for the suggestion. I tried it as well as autoclean. But to 
no extent.

OTOH, all 'apt-get' commands from a terminal work correctly. It's 
synaptic, which does not work. Just a minute ago i realized that also 
gdebi-gtk will not work. I got this error, repeating the operation i'd 
tried before in desktop environment out of a terminal:

-----

Seems pretty much the same as for synaptic.

What is a Gtk.main_interation? And what a segmentation fault?

Thanks a lot in advance for your patience!
