--- Comment #4 from wokim <mequer...@gmail.com> --- (In reply to Nate Graham from comment #3) > Can you please attach a backtrace of the crash? See > https://community.kde.org/Guidelines_and_HOWTOs/Debugging/ > How_to_create_useful_crash_reports I tried attaching gdb to a running plasmashell process, but after entering 'continue' in gdb, plasmashell freezes or crashes. So I started a new plasmashell process with gdb, which does work and lets me trigger the bug. But after the bug makes plasmashell crash, entering 'thread apply all bt full' in gdb returns nothing and 'bt' returns "No stack.". Reading symbols from plasmashell...
