From 03c016bea939ee4a26e90d80fa1012a993a8ea47 Mon Sep 17 00:00:00 2001 From: Victor Toso Date: Fri, 14 Oct 2016 18:12:01 +0200 Subject: clipboard: Fix crash by handling error As manual states below, text could be NULL for different reasons and we should handle that. I've included a debug message to help identifying possible regressions from wayland's clipboard. This crash is a regression from 7b0de6217670e0f668aff2949f "The text parameter to callback will contain the resulting text if the request succeeded, or NULL if it failed. This could happen for various reasons, in particular if the clipboard was empty or if the contents of the clipboard could not be converted into text form."
