Absolutely not; this is a bug in your code (more exactly a missing call
to g_io_channel_set_flags()); check the documentation for proper usage
of this function.

Also, application development questions should be raised on
gtk-app-devel-list (and think of the vast amount of gtk+ based software
out there, it's quite unlikely that you hit a massive bug like this).
