Good catch. I can reproduce this in 1.27 (experimental), but not in
1.26 (unstable) and 2.2.3 (pending experimental), so this is going to
solve itself with the next upload.

Bug#832598: atop: segfault; proc filtered, threads on, cursor left

2016-07-27 Thread Ph. Marek
Package: atop
Version: 1.27.3-1
Severity: normal

I can crash atop reliably and reproducible with this sequence:

 * start atop
 * filter by some process name ("P"); must fit fully on the screen
   (eg.  "acpi")
 * show threads ("y")
 * cursor left
 * BOOM

No -dbgsym on http://debug.mirrors.debian.org/debian-debug/, so only this 
information is available:

But if it's as reproducible for you it should be easy to fix and/or find.
