Bug#384894: Not able to exit via close window button in xfce4

[Johan Mattsson <johan.mattsson.6655@student.uu.se>]

Package: amsynth
Version: 1.1.0-2+b2

I amsynth does not exit when invoking the window close command (the
window x button). This happens with xfce4 4.2.3 and xserver-xorg
6.9.0.dfsg.1-5 and only when starting the shell script responsible for
copying configuration files instead of the amSynth.bin file.

In other words the command "kill amsynth" kills the shell script but
keeps the amsynth.bin binary and the window running.
