Yes. You are casting the _RESULT_ of a _CALL_ to ReadData into a GSourceFunc, but ReadData returns void. This produces utterly random results.
The second argument of g_timeout_add_seconds is a function pointer, and requires that you pass it a simple C function reference _without_ the call syntax.
Cheers,
Rob
