OK, so we know now for sure, the problem has to be the config file itself or the GUI.

Please try this as root:

openvpn --config /etc/openvpn/Home.conf

If this is working, there is something wrong with the GUI.
If this fails, then I have to start guessing. Things you could try:
- get hexdump to the phone or the config file to the PC and look into the file with a hexeditor
- create a complete new file with vi on the phone
- chmod 644 /etc/openvpn/Home.conf
- chown root:root /etc/openvpn/Home.conf
- renaming Home.conf to something like home.conf
