With threads shown, processes filetered to show one process only, atop crashes when trying to switch figures to "scheduling and thread-group info". Reproducible: Always Steps to Reproduce: 1. Start atop with neither special config nor command-line options 2. Filter the processes (using 'P' "processname" <Enter>) to show only one process (I used "firefox") 3. Show threads (using 'y') 4. Switch to scheduling and thread-group info (using 's') Actual Results: atop segfaults Expected Results: atop shows scheduling and thread-group info After filetering, there must be some process shown, when filtering with a regexp that matches no processes, the crash doesn't occur. However, I haven't tried filtering with regexp that matches more than one process.

This does not happen any more with =sys-process/atop-2.1.
