Nos últimos dias, alguns aplicativos da área de trabalho começaram a morrer sempre que as teclas Ctrl , Alt ou Shift são pressionadas ou a GUI é clicado com o botão direito do mouse. Isso acontece no keydown / mousedown.
Por exemplo, acontece em:
Isso não acontece em todos os aplicativos. Por exemplo, o Chrome, o Clion (IDE), o Skype e o gitk não são afetados.
Se eu iniciar nautilus da linha de comando, pressione Ctrl :
$ nautilus
Segmentation fault
A execução com gdb mostra o seguinte backtrace:
