Created attachment 179859 [details] Adding journalctl, if it can be useful
If something crashed, we need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash using the coredumpctl command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl? Thanks!
Hello, Ubuntu doesn't have coredumpctl because it uses apport and, in this case, apports doesn't report any bug. I tried to create a backtrace using "gdb --args plasmashell --replace" but nothing seems to crash. The problem occurred, but the crash has not been reported by gdb.
