After a reboot everything worked. Ít could have been caused by an update of some packages.
I can confirm this. New equivalent crash windows keep popping up in seemingly regular intervals (several minutes), regardless of whether I had closed the previous ones, such that I might well end up with a dozen windows cluttering up my screen if I don't care to click them all away. Very annoying! (On Kubuntu, I had to install the apper-dbg and packagekit-dbg packages to get debug symbols.)
