External encoder will not shutdown when liquidsoap is killed

On 0.9.2-2 on FreeBSD 7.1 i386

When I send liquidsoap a kill signal when it is in the background, or ctrl-c when it is in the foreground it will not shutdown. Instead it keeps restarting the external encoder:

As you can see, every time I send it a ctrl-C (or a kill signal when in the background) it continues to restart the aacplusenc encoder over and over again rather than killing the whole liquidsoap program.
