I am using Debian Lenny with KDE and I get the problem with the *.deb from the official repository (1.0.0) and also with the self-compiled version 1.0.6.

I start the program, all is doing very well.
But every time I start the game, gnujump freezes and nothing can be done. It happens the most times just at the beginning or latest when I do the first jump. So I can walk right and left without problems.
After that, I have to kill the program or I can make the program wait in the background with "CTRL+Z" and then resume with "fg" if I start it in a console. I have to redo this every time after I died.
Sometimes the game also freezes when I am in the menu.

I am not sure if this has an relation with my problem, but sometimes I am also getting "write /dev/sequencer or /dev/snd/seq: Bad file descriptor" and one time I had a "segmentation fault".

I attached the output of my console. The "Speicherzugriffsfehler" is the segmentation fault.
