Bug#824603: meld gives python traceback on first use after installation.

Thu Dec 1 02:36:35 UTC 2016

Hi,

the exception occurs since commit [1]. Not only GtkShortcutsWindow, but
also set_help_overlay() function for GtkApplicationWindow have been
introduced in GTK+ 3.20 [2].

No requirements bump needed. Please try the patch, I've proposed on [3].

Thanks,
Andrey
