https://bugs.kde.org/show_bug.cgi?id=3D387548 --- Comment #3 from Antonin Roussel --- Created attachment 109607 --> https://bugs.kde.org/attachment.cgi?id=3D109607&action=3Dedit gdb backtrace I did attach gdb to plasmashell process from my user terminal, I got many m= any errors like in the ten first lines, then I needed to continue the interrupt= ed process [(gdb) c] I made a jump in the menu, and then I got the line : Thread 1 "plasmashell" received signal SIGSEGV, Segmentation fault. following lines may give you clues. Let me know if it's not sufficient. At the end plasmashell has restarted itself, after a black desktop (with applications still running over) --=20 You are receiving this mail because: You are watching all bug changes.=
