Based on the symptoms, I would assume that you didn't fork before
you executed the program from the home plugin.  I.e. basically
you replaced Desktop process with "pplay" process.  When "pplay"
exited, from the system point of view that was then as the Desktop
had exited and device software watchdog rebooted the device.

You might either use the Glib convenience functions for executing
the process, or execute the process as Desktop runs applications,
i.e. as D-BUS services (D-BUS then takes care that there's only
one instance of the service running/in-memory, not the application
itself).
