I have some information to better reproduce this problem:
If I do in Brasero:
1) Open Edit -> Plugins
2) Uncheck only *some* plugins
3) close dialog
4) open it again (Edit -> Plugins)
there would be correctly checked items exactly as I have set them,
but if I do:
1) Open Edit -> Plugins
2) Uncheck only *ALL* plugins
3) close dialog
4) open it again (Edit -> Plugins)
then there would be all plugins checked instead of unchecked.

Do you experience the same as this?
