This morning I found my computer on the login screen. But not the one of the screen log, no a new one - so something must have crashed. Logging in again confirmed that all apps were gone and the gnome shell was brought down what seems like triggered by a background update o accountsservice. As always things are not perfectly clear :-/ The following goes *back* in time through my logs one by one. Multiple apps crashed at 06:09, but we will find later that this is a follow on issue of the underlying gnome/X/... recycling. -rw-r----- 1 paelzer whoopsie 52962868 Apr 8 06:09 _usr_bin_konversation.1000.crash -rw-r----- 1 paelzer whoopsie 986433 Apr 8 06:09 _usr_lib_x86_64-linux-gnu_libexec_drkonqi.1000.crash rdkit was failing fast and giving up (that will be a different bug, it just seems broken on my system): Apr 08 06:10:13 Keschdeichel systemd[1]: Started RealtimeKit Scheduling Policy Service.
