--- Comment #5 from el elton@schiert.net 2009-06-16 05:31:14 --- Yes, I also get a lot of log events when I hold down space. The crash on exit is related to bug 18916 and is fixed by Henri's patch.
I tried key repeat settings like yours and also some other settings but it always worked for me.
What happens if you bind jump to a key that never repeats (like Shift)? Does it start working?
