It's really complicated ;)
When I first saw libbonoboui/doc/control.txt I thought it was just some
implementation notes and didn't read it. It does not look like a must
read doc...

A simple doc explaining how to use the bonobo_object_ref/unref alongside
g_object/ref/unref would be very useful IMHO, currently it's quite hard
to know what happens.

No, I was not doing this. I had tried doing a g_object_unref here (it
didn't work, of course). Thank you, it seems that things work correctly
now.
