Re: g_main_dispatch frees objects for input_callback before using them (how to prevent it?)

Thank you for your responses!

I changed that, the diff is now:
https://github.com/XQF/xqf/compare/master...g_io

But the bug is still there. ;-)

The problem is when I call "g_io_addwatch (chan, condition, callback, user_data)",
"g_io_add_watch" calls "g_io_add_watch_full (chan, condition, callback, user_data, and more)", ok.

But after that, g_main_dispatch calls "callback(bad pointer user_data, bad pointer condition)", not ok.

I fixed the return of the callback, but the callback fails before returning anything… g_main_dispatch pass wrongs arguments to the callback. :/

It seems something is lost somewhere…

(and yes it is a very old and very deprecated code, that's why I'm working on it. :D)
