Fread doesn't distinguish whether there is an EOF condition in the input or just zero bytes read. So it is important to read in "blocking mode" (which is the default anyway). The disadvantage is, of course that if the popened program hangs for a while so will the graphical application. The alternatives I see are (a) decoupling via a temp file (as your original approach suggested) or (b) opening in non-blocking mode and handling zero-byte-reads more carefully (with select() or actually the glib wrappers for this g_io_channel_xxx()).
