Re: libseed-list Gtktextview.js sample crashes. How to debug? How to help?

["Alan Knowles" <alan akbkhome com>]

I think it's all fixed in the development version.

This should be quite up-to-date for a ubuntu distribution.
https://github.com/roojs/gir-1.1/blob/master/Gtk-2.0.gir

after modifying the gir file do this.

g-ir-complier Gtk-2.0.gir -o  /usr/lib/girepository-1.0/Gtk-2.0.typelib 

That should fix the segfaults.

Regards
Alan
