Brasero GObject Introspection Completely Broken

Tested this on

but I've reproduced (and fixed) this in other distros using latest Brasero from git. After installing gir1.2-brasero these are some of the issues

# apt-get install gir1.2-brasero

I've sent a patch to a similar bug report upstream at

https://bugzilla.gnome.org/show_bug.cgi?id=646069

but upstream obviously does not care about this. The question is whether this can be fixed at the package level to have working GObject Introspection in Ubuntu or should we wait forever for upstream to take care.
