I get the following report when using Gtk.selected_rows()

[johntrinder]

I am using the code supplied in the docs but have had to search around for using multiple selections in a TreeView
The code portion I have used is:
...
selection = GAccessor.selection(trvw) # a GtkTreeSelectionLeaf
selection = GAccessor.mode(selection,Gtk.GConstants.GtkSelectionMode.MULTIPLE)

signal_connect(selection, "changed") do widget
if hasselection(selection)
global currentIt = Gtk.selected_rows(selection) # crashes REPL
println(currentIt)
# global currentIt = selected(selection)
# ix = Gtk.index_from_iter(str, currentIt)
# # now you can to something with the selected item
# println("index=$ix Text: ", str[currentIt,1], "\nImage: ", str[currentIt,2])
end
end
...

Please submit a bug report with steps to reproduce this fault, and any error messages that follow (in their entirety). Thanks.

The crash in selected_rows was recently fixed (#620) but hasn't been released yet. I think a release will happen soon. Hopefully that will solve your issue.

Thankyou
