Bug in Gtk::Treeview#row_expanded

Hi:

I don’t know where to report these bugs. Please let me know.

I found this bug when using Gtk::Treeview#row_expanded. The method
doesn’t return a valid iter.

def self__row_expanded(view, iter, path)
#iter = model.get_iter(path)
VR::msg( iter[2] )
end

This causes this error:

/home/eric/.rvm/gems/ruby-2.3.0/gems/gtk3-3.0.8/lib/gtk3/tree-iter.rb:28:in
get_value': undefined methodget_value’ for nil:NilClass

If I uncomment the line where I reassign the iter variable using the
model#get_iter method, it works perfectly.

I’d like to work more closely with the people who work on Ruby/Gtk.
Please let me know who you are.

Thanks for all your great work!

Eric
