mouseconfig sets MOUSETYPE (in /etc/sysconfig/mouse) to "MouseMan" for a Logitech MouseMan mouse. It should be set to "mman" instead. Although "MouseMan" is a synonym for "mman" according to the gpm documentation, "MouseMan" causes gpm to segfault, whereas "mman" works flawlessly. I'm using gpm-1.19.0-3 and mouseconfig-4.5-1.
This should be fixed in gpm-1.19.1-1, which should be in the next rawhide release.
