From: Victor Toso <>

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
