+Subject: [PATCH] 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."
+
+Resolves: rhbz#1384676
