From 2b47afadc0fcc9a2617d5c9e8be0ee035762e0b9 Mon Sep 17 00:00:00 2001 From: Frank Richter Date: Wed, 12 Jul 2017 17:15:10 +0200 Subject: gtk3: Disable native file dialogs on GTK3 < 3.15.5 Showing file dialogs if running on a system that has an older GTK3 version installed results in a crash. Do a version check at runtime and disable native file dialog support if the version is too old.
