Re: [Gnash-dev] --once parameter regression

[Sandro Santilli]

This may be related to a bug filed for fscommand:quit being ignored when found
in first frame. The bug there is that the GTK main loop isn't started
at time of gtk_quit
call. The assertion you get from GTK seems to be the same...
Just an hint to help  you looking at it.
