gnome-tweaks crash when Shift is pressed

[Leonardo Müller]

If gnome-tweaks window is focused and shift is pressed, it crashes and the following appears on dmesg:

[16089.429921] gnome-tweaks[26081]: segfault at f0 ip 00007f45810351e2 sp 00007fffdb4d8988 error 4 in libgdk-3.so.0.2200.30[7f4580fee000+eb000]

I have tested with notebook's keyboard and an USB keyboard. All 4 Shift keys make gnome-tweaks crash.

This issue does not affect me under the description that you have supplied. I have tried holding down the left click and pressing the shift key a few times while still holding down the left click, pressing the shift key alone if while the window was in focus and clicking around the application's graphical interface while holding down the shift key at the same time. It was also within the Wayland session (just noticed the tag). If you send a more detailed description of your actions that led up to the crash, I will try to recreate the crash according to those directions. Have a nice day!

Maybe the issue is related to the ABNT2 keyboard layout, so it doesn't happen everywhere. If it happened with all keyboard layouts, probably it would have been noticed.

From my limited knowledge in French, I assume the error reads "segmentation fault" in the top right terminal. Here's an in-depth Wikipedia article: https://en.wikipedia.org/wiki/Segmentation_fault

It seems that it could be caused by a combination of your hardware and software, different software present on the system, a combination of both, maybe that plus a bug that only reveals itself in rare cases, ...

It might be better if you would report this issue on GitLab (there was also a GitHub repository, but the last updates were five years ago, while it is a few months on GitLab, so I would assume that the GitLab one is the currently active one, https://gitlab.gnome.org/GNOME/gnome-tweaks/issues ).

I am sorry that I couldn't have helped you at all, but I wish you the best of luck! Have a nice day!
