Program crashes with SIGSEGV when buttons-per-row is set incorrectly

[Eoghanmc22]

When running wlogout version 1.2.2 on nixos, if the number of buttons per row is set incorrectly, the program creates ghost buttons, and when they are selected with keyboard, the program crashes with a seg fault.

I also encountered something similar. I published some patches to address this #71
