PDF viewer Send by E-mail not working

Version: Linux Mint 17.3 64 bit Cinnamon

How to reproduce the issue : Open up a PDF file with Evince , Click on File > Send to . You will get
an error saying : Could not send current Document. Failed to execute child process "(null)" (No such file or directory)

I suspect that this is the solution lies here: http://askubuntu.com/questions/566053/how-to-make-evince-send-to-work-with-thunderbird-in-xubuntu-lts

After I corrected the symlinks, as shown in the 2nd answer from the top, it works fine :

Hitting File > Send To ... evince is looking for a nautilus-sendto executable. If not available the 'send to' command fails.

If you don't have or want or can install nautilus-sendto you can setup an alternative script to send documents to Thunderbird:

nano /opt/evince-send-to-thunderbird
>>>
#!/bin/bash
thunderbird -compose "attachment='$1'"
<<<

chmod 775 /opt/evince-send-to-thunderbird
ln -s /opt/evince-send-to-thunderbird /usr/bin/nautilus-sendto

After a restart of evince the fake nautilus-sendto script is found on the path and the 'send-to' command opens a Thunderbird Compose window with the current document as an attachment.

The problem occurs with fresh installs, haven't tested with MATE,XFCE or KDE versions.
