Problems with treeview selection when using multiple treeviews (libglade2)

[<Jo...@bo...>]

Hi

I have 2 problems to report.
The first one is that the procs sent to
Gtk::Treeveiw::Selection.set_select_function seems to be overwritten in
some cases if there are multiple treeviews. I cannot exactly point out
when, but it seems the storage of the procs is bogus in some way. There is
a workaround for this problem that goes like this:

my_sel_func = proc {|bla bla bla| ... }
my_treeview.selection.set_select_function(&proc)

It seems that when the procs are stored as local variables first, they are
not overwritten.


The other problem arises in an app that has a notebook and some treeviews
on different pages. I click aruond a bit in one of them, the contents
change as expected. Then I switch to another page and try to select an
item in the other view with attached selection function. I then get a
"[BUG] Segmentation fault" The views are created from a glade file, but
the rest (model, columns, renderer and selection callback proc) is created
in the script. I'm not very experienced with ruby / mixing, but I guess
since I get a segfault it is in the c code the problem is. The first thing
may be then how to connect gdb to my app so that I can see where the
segfault comes from. Could someone please help me doing that?


My system specs is:
Redhat Enterprise 3.5
Gtk 2.2
ruby stable cvs snapshot
gnome2-ruby 0.13

I cannot attach the source, since I'm developing this for a big company
and they wont let the source outside their system.
