Perhaps, but a gboolean is most definitely not the same as a
GSourceFunc. So I shall reiterate:

^^
You are casting the _RESULT_ of a _CALL_ to ReadData into a
GSourceFunc, but ReadData returns bool. This produces guaranteed
illegal 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.
Unless you're now going to say that you'd misremembered that too, and
the actual code doesn't have the () after the frame->ReadData in the
line I re-quoted. It would really help us to help you if you had posted
your actual code rather than a misremembered vague approximation.
Cheers,
Rob
