Re: PSPP-BUG: bug report

[Ben Pfaff]

While investigating this report I found that I could reproducibly
get the following warning:

        GLib-GObject-WARNING **: invalid uninstantiatable type
        `(null)' in cast to `GtkTreeModel'

if I started psppire with a .sav on the command line, selected
Transform|Recode into Different Variables, clicked on a variable
in the dialog box, clicked on the > button, clicked on the
variable name in its new location.

Top of the backtrace is:

I don't see the same problem when I do similar actions in other
dialog boxes under Transform, such as Recode into Same Variables.

It's late and I'm tired so I'll give you the first shot at this
:-)

Thanks,

Ben.
