cannot reproduce segfault

I just tried on another computer (both are fully updated arch) and it worked there. I don't know if this is useful, but below is the output of gdb:

Hi, thanks for reporting this bug. Here is a guide for getting even better debug output, that may be helpful: https://wiki.archlinux.org/index.php/Step_By_Step_Debugging_Guide

I could not compile the package with !strip, because the PKGBUILD on ABS does not compile (now it even has missing sources, but I found another one)

But the full backtrace of the stripped binary is bellow:

Thanks, much better. Now one can see where the problem is located in terms of libraries as well.

Apparently, the problem appears in the gpds_xinput_utils_get_device_info() function in /usr/lib/libgpds.so.0.

However, without further information, it's hard to pinpoint exactly where in the code things go wrong.

I would recommend reporting this upstream, to the gpointing-device-settings developers. It's possible that this is a known problem that someone else has reported, in which case you will get more information about the problem that occurs on your computer too. If you do, please post a link to the bug report here.

Does the problem go away if you unplug your mouse (or other input devices) and plug in a different mouse?

It's an upstream bug, so please report this problem to the upstream developers:
