Two line breaks between message and quotation are missing

[Michael Korn]

With Ubuntu 16.04 and evolution 3.18.5.2 I observed that two line breaks (between my message and quotation) are removed after sending the message if I reply to a message. This happens with plain text messages since I updated from Ubuntu 14.04 3 weeks ago, I checked it in the "Sent" folder.

Examples:
I wrote:
"test1

test2

test3

..."

What is send and saved in the "Send" folder:
"test1

test2

In addition, in one message the line brakes were removed within my text. I wrote:
"...freundlichen Kontakt und die hilfreichen Telefongespräche.
