modelfilter + expand attribute

[Yann Leboulanger <asterix lagaule org>]

Hi all,

I have a treeview with rows and sub-rows. This treeview gets his data in
a treemodelFilter.

Now I collapse rows in thee treeivew, then, I run modelfilter.refilter()

Problem appears: rows that I collapsed are now expanded.

Is it a bug in GTK or normal behavior? Is there a way to change that, or
to workaround that?
