No problem, it always confuses me after I haven't been using a TreeView

I'm glad you got it working! :)

OK thanks.

to the columns.

While I have no idea about the problem at hand, is it not possible to
find the potential owners using a gdb conditional breakpoint like
https://developer.gnome.org/gobject/stable/tools-refdb.html ?


I'm not sure if that will help because I don't know the address of the 
widget instances in advance - I assume that everything that holds a ref 
to it will have it already soon after it is constructed and added to 
the UI.
