--- Comment #3 from Mahbod Karamoozian <[email protected]> --- (In reply to TraceyC from comment #1) > Thanks for the crash report. As the message at the top of the summary says, > 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. #0 0x00007f1498ca7a2c in ??
