Comment 1 Thomas Vander Stichele 2005-05-17 17:44:39 UTC

doing g_type_class_ref/unref during _init (when there's only one thread) seems
to fix it.

Comment 2 Thomas Vander Stichele 2005-05-17 17:50:43 UTC

fixed in head

Comment 3 Antoine Tremblay 2006-05-15 17:53:00 UTC

Do we know why this is ?

I was able to reproduce it with other types like : GLib-GObject-ERROR **: g_type_plugin_*() invalidly modified type `GstFormat'

I'll patch all mini_objects derived types with ref/unref but if I could understand a bit more how it helps it would be nice...

Thanks

Comment 4 Antoine Tremblay 2006-05-15 18:49:41 UTC

And i'm trying to figureout why this is limited to mini_object types... ?

Since GstFormat isn't one... but it's from a GstEvent so it could be somehow.. just if you know why it is limmited to them i'd like to know :)
