[gtkmm] small application segfaults with treeview & liststore & sroll_to_row()

[Florian Schmidt <schmidt_florian gmx de>]

hi,

i've spend hours to drill down my program to reproduce the problem.
the project (300k) can be downloaded here: http://212.18.25.243/flo/test_case.tar.gz

how to reproduce the segfault:
there is one entry in the treeview/treestore on the left, double click on it until
the other treeview/liststore at the bottom is filled. the next double-click will segfault. (every time)

my system:
debian (unstable)
gcc 3.3.4
libgtkmm-2.4 2.4.5-1
libgtk2.0 2.4.9-1

i will give more information if needed.

hope that someone can confirm/decline my problem.

it seems that it is a special case with these 3 widget:
	TreeView/TreeStore
	Notebook (with hide()/show() calls)
	TreeView/ListStore


here is the gdb backtrace:

maybe my code is silly, but i reduced it to a few lines, so it
must then be a problem in my understanding...

hope someone can fix it/ tell me what i am doing wrong...

p.s.: part of the source was generated from glademm but there
is not much left...

bye...
