solved for a few minutes ... it seems that the Gnome extension "Journal"
triggers the crash. Disabled it now, gotta monitor things.

Maybe it has to do with zeitgeist.

Just to be correct on that one:

removed "Journal" (and "Jump Lists") completely, re-added it.

It works fine now.

Both the extension itself and the "typing the first characters"-behavior
of the gnome-shell.
