[Gnash-commit] [bug #27981] fscommand:quit ineffective if in first frame

[Nutchanon Wetchasit]

Follow-up Comment #4, bug #27981 (project gnash):

First assertion error message seems to be caused by calling `gtk_main_quit()`
before the GUI code enters `gtk_main()`. I have created a dummy patch
which prints DEBUG message when `gtk-gnash` enter/terminate/exit main GTK
loop,
see the attached `show-gtk-main-loop-level.patch`.

After applied the patch, I tested using `gtk-gnash -vv singleframeexit.swf`:

151 DEBUG: GtkGui: starting GTK main loop


>From debug output, you'd see that Gnash tried to terminate main GTK loop
before
the main loop is run, so it failed. When the GTK main loop is run afterward,
there were nothing else to stop it, so Gnash simply froze instead of exiting.
