I am currently working with the evince 3.10.3 document viewer on Xubuntu LTS 14.04.
When I hit File > Send To..., I receive the following error message from evince:
Could not send current document
Failed to execute child process "(null)" (No such file or directory)
Nevertheless, I have Mozilla Thunderbird defined as the Mail Reader in Preferred Applications under Settings Manager.
What else should I configure?
