This works. Disconnecting the "model" from the "view" before doing
clear is the key. But very uncomfortable.
What not worked was to unselect before doing clear. I don't understand
why.
This all sounds to me like a mystic behaviour what could be a bug. But
I am not deep enough into Gtk so I won't open an official report about
this. It is on the core devs and experts in that list to decide if this
is an serious issue or not.
kind
Christian
